Lambi, John N. published the artcileSynthesis, spectral properties and thermal behaviour of zinc(II) acetylsalicylate, Recommanded Product: 9-Phenyl-9H-xanthen-9-ol, the publication is Thermochimica Acta (2003), 398(1-2), 145-151, database is CAplus.

The thermal behavior of Zn(II) acetylsalicylate [Zn(acsa)₂(H₂O)₂] with respect to phase transitions, pyrolysis both in air and inert (N₂) atm., and product identification was studied. The complex was synthesized by metathesis in hot EtOH solution using aspirin (acetylsalicylic acid) as precursor and characterized via electronic and IR spectral analyses. Optical observations showed that the white salt does not undergo a direct transition from the solid to the liquid phase but rather goes slowly through an intermediate mesophase around 80° before melting rapidly to the brick-brown isotropic liquid around 134-136°. No liquid crystalline phases are however formed. This result was complemented by that from thermogravimetric (TG) studies in the ∼25-600° range, which showed three main weight-loss phases of 8.0, 50.0 and 14.0% (around 200, 250 and 400°) corresponding, resp., to the elimination of CO₂, xanthone and HOAc. The pyrolysis products, as identified using a combination of instrumental (GC-MS) and wet chem. techniques are: CO₂; nonstoichiometric Zn oxide, most likely in the form: Zn_1+xO (0.0000 ≤ x ≤ 0.0003); and a mixture of organic products resulting from further decomposition, charring and other attendant thermal effects at the relatively high temperatures (∼600°) involved. Six of the principal organic products were identified and included salsalate and benorylate which are pro-drugs of salicylic acid, a known pharmaceutical.

Chateauneuf, John E. published the artcileAn investigation of Friedel-Crafts alkylation reactions in super- and subcritical CO₂ and under solventless reaction conditions, Application of 9-Phenyl-9H-xanthen-9-ol, the publication is ACS Symposium Series (2002), 136-150, database is CAplus.

A symposium report. The Friedel-Crafts alkylation reaction of triphenylmethanol with methoxybenzene in supercritical and subcritical carbon dioxide, and under solventless reaction conditions was investigated. The reaction was initiated using trifluoroacetic acid to produce triphenylmethlycarbocation as the reaction intermediate. Isolated product yields of the Friedel-Crafts product, p-methoxytetraphenylmethane, are reported. The possibility of using the above reaction as an alternative synthesis in an undergraduate organic laboratory to teach some of the tenets of green chem. was also investigated. Addnl., the use of benzhydrol, 9-hydroxyxanthene and 9-phenylxanthen-9-ol as potential carbocation sources for supercritical carbon dioxide synthesis was studied and preliminary results are reported.

Various multi carbon homologations of 9-phenyl-9H-xanthen-9-ol were obtained through a C-C bond formation by reacting it with various enolizable ketones in the presence of 1,1′-(ethane-1,2-diyl)dipyridinium bistribromide (EDPBT). All the ten derivatives along with the starting xanthen-9-ol have been characterized by single crystal X-ray diffraction. They all form self-assembled superstructure in the solid state. The self-assembling patterns in these supramol. architectures were explained based on steric and electronic nature of the pendant arm.

Regioselective C-C bond formation of 9-phenyl-9H-xanthen-9-ol 1 with various enolizable ketones I-X in an acidic (HBr) medium, obtained by the reaction of 1,1′-(ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) with ketone is observed Except for ketone, 4-methyl-pentan-2-one VII in all other cases examined the attack to xanthenyl carbocation is from the thermodynamically stable enolizable side of the unsym. ketones. In the case of 3-methyl-butan-2-one VIII the equilibrium is in favor of the more stable enolizable ketone, which has large steric factor, hence no reaction was observed during its addition to alc. 1.

Alkyl-substituted alkenes have been epoxidized with 9-hydroperoxy-9-phenylxanthene in the presence of molybdenum(0) hexacarbonyl as catalyst, in moderate yields. Excellent yields of chalcone epoxides were obtained by epoxidizing a series of substituted chalcones with the hydroperoxide in basic nonaqueous medium.

Goosen, Andre published the artcileReactions of 9-hydroperoxy-9-phenylxanthene: oxidation of sulfides, sulfoxides, and thiols, Recommanded Product: 9-Phenyl-9H-xanthen-9-ol, the publication is South African Journal of Chemistry (1989), 42(3), 107-12, database is CAplus.

Sulfides have been oxidized selectively to sulfoxides with 9-hydroperoxy-9-phenylxanthene at ambient and reflux temperatures resp. Excellent yields of dialkyl and aralkyl sulfoxides were obtained; diaryl sulfides gave moderate-to-poor yields of sulfoxides. Selective oxidation of allyl Ph sulfide to form sulfoxide without epoxidation was accomplished. These reactions have been proposed to proceed via a heterolytic path which does not involve the intermediacy of the hydroperoxy anion. Trifluoroacetic acid, benzyltrimethylammonium hydroxide, and molybdenum(0) hexacarbonyl catalyzed the oxidation reaction to give high yields of sulfoxides or sulfones, depending on the reaction conditions. Mechanistic aspects of these catalyzed oxidations have been discussed. Advantages of the reaction include the ease of separation of the peroxidic ancillary products from the formed sulfoxides and sulfones, as well as the relatively high stability of the hydroperoxide as compared to other known peroxide reagents.
