Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Canadian Journal of Chemistry called Photochemistry of matrix-isolated 5-cyano-2H-pyran-2-one (δ-cyano-α-pyrone) and cyanocyclobuta-1,3-diene, Author is Menke, Jessica L.; McMahon, Robert J., which mentions a compound: 1195-58-0, SMILESS is N#CC1=CC(C#N)=CN=C1, Molecular C7H3N3, COA of Formula: C7H3N3.

Matrix-isolation photochem. (λ > 299 nm; Ar, 10 K) of 5-cyano-2H-pyran-2-one (5, δ-cyano-α-pyrone) shows complete conversion to a mixture of several ring-opened ketene isomers (6) and a ring-closed Dewar lactone (7), as detected by IR spectroscopy. Subsequent irradiation (λ > 200 nm) causes decarboxylation of the Dewar lactone (7) to produce cyanocyclobuta-1,3-diene (8). Continued irradiation (λ > 200 nm) results in the photodecomposition of cyanocyclobuta-1,3-diene (8) to cyanoacetylene and acetylene. 4-Cyanopyridine (10) was explored as an alternative photochem. precursor to cyanocyclobuta-1,3-diene (8). It was found, however, that 10 does not exhibit observable photochem. under our irradiation conditions.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Nucleophilic substitution of aromatic chlorine in diazonium ions by bromide ions》. Authors are Lamm, Bo.The article about the compound:3-Bromo-4-chloronitrobenzenecas:16588-26-4,SMILESS:BrC1=C(C=CC(=C1)[N+](=O)[O-])Cl).HPLC of Formula: 16588-26-4. Through the article, more information about this compound (cas:16588-26-4) is conveyed.

To determine why a Cl atom in a suitably substituted diazonium ion should not be replaced by a Br- ion, the reaction of 2-chloro-5-nitrobenzenediazonium ion in an HBr-AcOH-H2O medium at 25° was studied. It was found that some of the aromatic Cl is “”frozen in”” and no quant. conversion of aromatic Cl to Br can occur; the reverse reactions are considerably more rapid than the forward ones, so that a small amount of Cl- ions generated in the exchange reaction produces an equilibrium containing comparable amounts of each, despite the large excess of HBr; and the equilibrium is continually being disturbed by the side-reactions, which cannot be suppressed by increasing the Br- ion concentration

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 438630-64-9, is researched, SMILESS is ClS(=O)(=O)C1=CNN=C1, Molecular C3H3ClN2O2SJournal, Article, Journal of Medicinal Chemistry called Identification of the Clinical Candidate (R)-(1-(4-Fluorophenyl)-6-((1-methyl-1H-pyrazol-4-yl)sulfonyl)-4,4a,5,6,7,8-hexahydro-1H-pyrazolo[3,4-g]isoquinolin-4a-yl)(4-(trifluoromethyl)pyridin-2-yl)methanone (CORT125134): A Selective Glucocorticoid Receptor (GR) Antagonist, Author is Hunt, Hazel J.; Belanoff, Joseph K.; Walters, Iain; Gourdet, Benoit; Thomas, Jennifer; Barton, Naomi; Unitt, John; Phillips, Timothy; Swift, Denise; Eaton, Emily, the main research direction is glucocorticoid receptor antagonist CORT125134 preparation Cushing’s.Electric Literature of C3H3ClN2O2S.

The nonselective glucocorticoid receptor (GR) antagonist mifepristone has been approved in the U.S. for the treatment of selected patients with Cushing’s syndrome. While this drug is highly effective, lack of selectivity for GR leads to unwanted side effects in some patients. Optimization of the previously described fused azadecalin series of selective GR antagonists led to the identification of CORT125134, which is currently being evaluated in a phase 2 clin. study in patients with Cushing’s syndrome.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Room-Temperature Phosphorescent Platinum(II) Alkynyls with Microsecond Lifetimes Bearing a Strong-Field Pincer Ligand》. Authors are Liska, Tadeas; Swetz, Anna; Lai, Po-Ni; Zeller, Matthias; Teets, Thomas S.; Gray, Thomas G..The article about the compound:Dichloro(1,5-cyclooctadiene)platinum(II)cas:12080-32-9,SMILESS:C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-]).Related Products of 12080-32-9. Through the article, more information about this compound (cas:12080-32-9) is conveyed.

The use of organometallic triplet emitters in organic light emitting diodes (OLEDs) is motivated by the premise of efficient intersystem crossing leading to unit internal quantum efficiencies. However, since most devices are based on solid-state components, an inherent limitation to square-planar Pt(II) phosphors is their tendency toward aggregation-based quenching. Here, a new class of emissive, four-coordinate Pt(II) species based on the bisimidazolyl carbazolide (BIMCA) ligand is introduced, which displays highly efficient, long-lived solid-state phosphorescence at room temperature A set of four BIMCAPt Ph acetylides were synthesized that emit in the green (λmax=507-540 nm) with >60% quantum yield and millisecond lifetimes. The structures of the resulting species reveal a nonplanar structure imposed by steric clashes between BIMCA and the iodo or alkynyl co-ligand. Ground-state and photophys. characterization are presented. D. functional theory calculations indicate that the BIMCA ligand dominates the frontier orbitals along with the 1st Franck-Condon singlet and triplet excited states.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 3-Bromo-4-chloronitrobenzene, is researched, Molecular C6H3BrClNO2, CAS is 16588-26-4, about Acid- and base-dependent hydrolysis of N-(sulfonatooxy)-3-bromoacetanilide: involvement of N-(3-bromophenyl)hydroxylamine O-sulfonate, the main research direction is hydrolysis sulfonatooxybromoacetanilide kinetics; catalysis acid base hydrolysis sulfonatooxybromoacetanilide; bromophenylhydroxylamine sulfonate hydrolysis intermediate; carcinogenic metabolite model.Recommanded Product: 16588-26-4.

The title compound (I) undergoes hydrolysis at 80° and pH 1.0-8.0 by acid- and base-dependent processes and by an uncatalyzed path. The uncatalyzed reaction exhibits the same characteristics as the uncatalyzed N-O bond-cleavage reactions of the more reactive N-(sulfonatooxy)acetanilides. The pH-dependent paths involve the hydrolysis of I to form N-(3-bromophenyl)hydroxylamine O-sulfonate (II). II cannot be directly detected under the conditions of this study, but its existence can be inferred from product study and trapping data. Although II undergoes decomposition entirely by heterolytic N-O bond cleavage to yield m-BrC6H4N+H (III), a less reactive analog of II, i.e., N-(3-bromophenyl)-O-pivaloylhydroxylamine (IV), apparently undergoes competitive homolytic and heterolytic N-O bond cleavage to yield both m-NHC6H4Br radical and III. Both II and IV serve as models for certain suspected carcinogenic metabolites of polycyclic aromatic amines and amides.
