This article reports a study of excited-state hydroxide ion release from a model xanthenol photobase, XanOH. The driving force for the reaction was tuned using solvent mixtures with varying water/acetonitrile ratios, and the kinetics of the reaction was monitored using ultrafast pump-probe spectroscopy. The intrinsic barrier for the heterolysis was evaluated using Marcus and bond-energy bond-order (BEBO) models. The obtained value (ΔG^#_o = 10.17-10.80 kcal/mol) is significantly higher than the intrinsic barriers found for the proton release from previously studied photoacids. These results were discussed in terms of the difference in structures of solvated H⁺ and OH^– ions.

Zhou, Pan published the artcileMolybdenum-Catalyzed Cross-Coupling of Benzyl Alcohols: Direct C-OH Bond Transformation via [2 + 2]-Type Addition and Elimination, Product Details of C19H14O2, the publication is Organic Letters (2022), 24(23), 4218-4223, database is CAplus and MEDLINE.

Traditional cross-couplings catalyzed by transition metal catalysts generally rely on the classic oxidative addition-transmetalation-reductive elimination process, which requires low-valent precious metals and an inert atm. and which initiates from carbon-alide or pesudo carbon-halide bonds. Herein, an unprecedented molybdenum-oxo-complex-catalyzed intermol. cross-coupling of benzyl alcs. has been reported. Various alcs. including primary, secondary, and tertiary substrates can proceed efficiently under these conditions. Several functional groups sensitive to the low-valent transition metals, such as aryl halides, can be well tolerated. The mechanistic studies and DFT calculations suggest that an intramol. concerted cyclization was involved in the reverse [2 + 2]-type elimination process.

A series of 9-alkyl- and 9-aryl-substituted xanthylium cations (I; R = H, Me, Me₂CHr, cyclo-Pr, tert-Bu; II; R¹ = H, p-CF₃, p– and m-Me, p– and m-OMe) were generated from the corresponding 9-xanthenols in strongly acidic aqueous MeCH (2:1) solutions (39-78% H₂SO₄). Steady-state irradiation at 370 nm produced the excited cations, all of which were fluorescent in the 520-nm region. Fluorescence lifetimes varied considerably with acid concentration, from subnanosecond values at low acidity to 20-35 ns at high acidity. Stern-Volmer plots of Φ_F°/Φ_F vs. the free water concentration in these acid solutions gave linear plots in all cases, yielding k_q values in the 10⁶-10⁹ M^-1 s^-1 range, depending on substituents. For the 9-aryl systems, a plot of log k_q vs. a recently determined σ^hν scale was reasonably linear (r = 0.974) with a ρ value of -1.5, which is opposite in sign to that recently determined for H₂O quenching of the same cations in their ground states. Possible explanations for this surprising result are considered.

Substituent effects on the temperature dependence of primary kinetic isotope effects, characterized by ΔE_a = E_aD – E_aH, for two series of the title reactions in acetonitrile were studied. The change from ΔE_a â‰?0 for a highly rigid system to ΔE_a > 0 for systems with reduced rigidities was observed The rigidities were controlled by the electronic and steric effects. This work replicates the observations in enzymes and opens a new research direction that studies structure-ΔE_a relationship.

Ungnade, Herbert E. published the artcileCondensations of aromatic aldehydes and aryl carbinols with aluminum chloride and aromatic systems, Quality Control of 596-38-3, the publication is Journal of the American Chemical Society (1953), 3333-6, database is CAplus.

The reaction of aryl carbinols and aromatic aldehydes with aromatic hydrocarbons and excess AlCl₃ has been extended to include substituted benzyl alcs. as donors and mesitylene, Ph₂, and Ph₂O as acceptor mols. An unexpected reaction occurred in Ph₂O with formation of 9-phenylxanthydrol (I) from BzH, PhCH₂OH, or Ph₂CHOH. The formation of I in these reactions is unique since the oxygenated compounds apparently undergo condensation at the normally unreactive o-positions of the Ph₂O rather than cleavage. BzH (30 g.) added during 0.5 h. with stirring to 20 g. Ph₂ and 79 g. AlCl₃ at 60°, the mixture stirred 3.5 h. at 60°, decomposed, and steam-distilled, the nonvolatile fraction (32.39 g.) distilled in vacuo, and the distillate (6.02 g., 28%), b_0.001 170-210°, crystallized 3 times from ligroine gave diphenylanthracene (II), m. 202-3°, λ_maximum 230 mμ (log ε 4.65), 257.5 (4.97), 277.5 (5.09), 332.5 (3.67), 347.5 (3.91), 365 (4.01), 385 (3.89).

H₂O, and filtered, and the crude green solid washed with H₂O, dilute aqueous NaOH, and again H₂O, and recrystallized from 95% EtOH and dried in vacuo at 100° gave 1.02 g. (93.5%) diphenylanthraquinone, yellow needles, m. 270-1°. BzH (25 g.) added during 0.5 h. to 67 g. AlCl₃ in 60 cc. mesitylene, the mixture stirred 3.5 h. at 60°, decomposed and steam-distilled, the distillate taken up in C₆H₆, washed with saturated aqueous NaHSO₃ [the insoluble adduct gave 7.86 g. (31%) BzH (oxime, m. 32-3°)], and the C₆H₆ solution rectified yielded 1.0 g. (2%) xylenes, b₅₉₈ 140-50°, n_D²³ 1.4970, λ_maximum^EtOH 266 mμ (log ε 2.40), 8.7 g.

(4%) C₆H₂Me₄, b₆₀₀ 180-5°, n_D²³ 1.5105, λ_maximum 269 mμ (log ε 2.57); a portion (12.86 g.) of the nonvolatile residue (22.50 g.) refluxed with ligroine (b. 70-90°), the solution filtered from 2.74 g. insoluble material, the solution adsorbed on Al₂O₃, and the resulting 3 bands (blue fluorescing under UV light) eluted with ligroine gave 7.34 g. (45.7%) oily solid, m. 132-8°, which gave, after repeated recrystallization from ligroine, tetramethylanthracene, m. 148-8.7°, λ_maximum 338 mμ (log ε 3.45), 350 (3.66), 366 (3.78), 386 (3.68). BzH (25 g.), 67 g. AlCl₃, and 75 cc. Ph₂O treated in the usual manner, the steam distillate extracted with Et₂O, the extract washed with H₂O, dried, and distilled gave 1.2% unreacted BzH (b₁₉ 96-8°) and 44.3% recovered Ph₂O [identified as (p-H₂NSO₂C₆H₄)₂, m. 157-8°]; the semi-solid residue from the steam distillation taken into C₆H₆, washed, dried, and distilled gave 32.2 g. distillate; a 2.18-g. portion in C₆H₆ gave 4 distinct bands on Al₂O₃; the bulk of the product was contained in 3 bands which were eluted with C₆H₆ and gave 0.12 g. red viscous oil, 1.48 g. red-brown oil, and 0.46 g. I crystalline solid, m. 149-54° (from ligroine); distillation of the residue (9.55 g.) gave 4.15 g. red oil, b_0.001 190-210°, which solidified on standing to yield 3.02 g. I, m. 156-7° (from C₆H₆-ligroine); on distillation in vacuo of larger quantities of the residue, pyrolysis and reduction occurred to yield PhOH and 9-phenylxanthene. Similar results were obtained with PhCH₂OH and Ph₂CHOH as starting materials, the over-all yields of I being from BzH 15.5%, from PhCH₂OH 15%, and from Ph₂CHOH 27%. I, m. 157-8°, was also obtained in 76% yield from xanthone and PhMgBr. I dissolved with green-yellow color and fluorescence in concentrated H₂SO₄; it gave derivatives with semicarbazide (m. 206-7°), NH₂OH (m. 194-5°), and PhNHNH₂ (m. 127-8°); it was recovered unchanged from its reaction mixture with MeMgI, and with acylating and oxidizing agents under ordinary conditions; pyrolyzed at 282° it gave PhOH. I was reduced to 9-phenylxanthene (III), m. 142-3° (from ligroine), by a Clemmensen reduction (91.3%), by a Schmidt reaction (96.6%), and by refluxing with alc. HCl (87.7%); insoluble in concentrated H₂SO₄, gave oxidized with KMnO₄ in aqueous Me₂CO, I, m. 155-6° (from ligroine). Xanthone (IV) (5 g.) in dry C₆H₆ added to 0.025 mol PhCH₂MgCl in dry Et₂O, the complex decomposed with ice and aqueous NH₄Cl, and the resulting yellow oil triturated with petr. ether, recrystallized from ligroine, or chromatographed on Al₂O₃ yielded 89% crystalline benzalxanthene (V), yellow needles, m. 110-11°, yellow with green fluorescence in cold concentrated H₂SO₄.

VII (2.0 g.) in 100 cc. 95% EtOH hydrogenated at 30 mm. pressure with 3 g. Raney Ni and 1 drop 50% aqueous KOH as catalyst, the mixture filtered, the solvent removed, and the residue crystallized from petr. ether gave 1.70 g. (85%) p-PhOC₆H₄CH(OH)Ph (VIII), m. 75.8-6.9°. VII (20 g.) added to amalgamated Zn (from 100 g. Zn and 10 g.

X in 5 l. distillate during 1 h.; the binary mixture contained thus 0.0098% X. X (1 g.) and 10 g. PhOMe steam-distilled at 98°/605 mm. yielded 5 l. distillate in 1 h. containing 0.30 g. X. 3,4-(MeO)₂C₆H₃CH₂OH (0.148 mol) gave with 0.297 mol AlCl₃, and 150 cc. thiophene-free C₆H₆, by the general procedure, 1.34 g. guaiacol (phenylurethane, m. 134°) and 1.03 g. X, m. 211-12°. To 0.20 mol o-HOC₆H₄CH₂OH and 150 cc. C₆H₆ was added 0.40 mol AlCl₃ in small portions, and the mixture worked up as usual to give 0.61 g. PhOH and 2.47 g. X. To 10 g. LiAlH₄ in 180 cc. dry Et₂O was added with stirring 34.50 g. o-PhCH₂C₆H₄CO₂H, m. 110-11°, in 100 cc. Et₂O at such a rate as to keep the mixture refluxing gently, the mixture stirred 0.5 h. and decomposed cautiously with cooling with 100 cc. H₂O, and then with 10% aqueous H₂SO₄, and the Et₂O layer washed with 10% aqueous Na₂CO₃, dried, and evaporated to give 20.47 g. (64.5%) o-PhCH₂C₆H₄CH₂OH (XI), b_0.001 130-2°. XI (10 g.) in 50 cc.

Wada, Masanori published the artcileReactions of 1,8-Dimethoxy-9-phenylxanthen-9-ol in the Presence of an Acid, and Its Basicity, SDS of cas: 596-38-3, the publication is Bulletin of the Chemical Society of Japan (1999), 72(4), 779-785, database is CAplus.

In the presence of a catalytic amount of acid, the title xanthenol (1) reacted in acetone to give 1,8-dimethoxy-9-phenylxanthen-9-ylmethyl Me ketone. Analogous reactions were observed for Et Me ketone and acetophenone, but not for di-Et ketone. Propanal and butanal also reacted to give 2-(1,8-dimethoxy-9-phenylxanthen-9-yl)propanal and 2-(1,8-dimethoxy-9-phenylxanthen-9-yl)butanal, resp. In hot primary and secondary alcs.,1 was reduced to give 1,8-dimethoxy-9-phenylxanthene. 1 also reacted with methoxybenzenes, phenol, and N-alkylanilines to give 9-aryl-1,8-dimethoxy-9-phenylxanthenes. The basicity of 1, or the stability of the carbenium ion (pK_R⁺ = -0.81), was measured in hydrochloric acid and compared with those of related 9-arylxanthen-9-ols, such as 1,8-dimethoxy-9-(2,6-dimethoxyphenyl)xanthen-9-ol (1.14), 9-(2,6-dimethoxyphenyl)xanthen-9-ol (4.80) (8), and 9-phenylxanthen-9-ol (0.75). The drastic differences in the reactivities and the basicity between 1 and 8 were attributed to a steric effect rather than an electronic effect.
