Synthesis and Structures of Bis(pentafluorophenyl) Selenoxide / Telluroxide
Bis(pentafluorophenyl) selenoxide and telluroxide were prepared by oxidation of the corresponding selenide and telluride with m-chloroperbenzoic acid. (C6F5)2SeO crystallizes in the triclinic space group P1̄ with a = 9.9452(9), b = 14.871(2), c = 15.279(2) Å, a = 117.17(1), þ = 101.02(1), þ = 95.39(1). The telluroxide (C6F5)2TeO crystallizes as a dichloromethane or benzene solvate. The crystallo...
متن کاملDiaryl and Heteroaryl Sulfides: Synthesis via Sulfenyl Chlorides and Evaluation as Selective Anti-Breast-Cancer Agents
A mild protocol for the synthesis of diaryl and heteroaryl sulfides is described. In a one-pot procedure, thiols are converted to sulfenyl chlorides and reacted with arylzinc reagents. This method tolerates functional groups including aryl fluorides and chlorides, ketones, as well as N-heterocycles including pyrimidines, imidazoles, tetrazoles, and oxadiazoles. Two compounds synthesized by this...
متن کاملManganese and Cobalt Salts of Para-Amino-Benzoic Acid Supported on Silica Gel as Oxidizing Catalysts
Para-Aminobenzoic acid is supported on silica gel via reaction of activated silica gel and p-aminobenzoic acid which is then converted to its manganese and cobalt salts. A mixture of the manganese and cobalt salts of the acid is used to catalyze allylic and benzylic alcohols to their corresponding carbonyl compounds in reasonable yields using oxygen or air. Reactions are clean and the catal...
متن کاملSynthesis and Effects of 4,5-Diaryl-2-(2-alkylthio-5-imidazolyl) Imidazoles as Selective Cyclooxygenase Inhibitors
Objective(s) In recent years highly selective COX-2inhibitors were withdrawn from the market because of an increased risk of cardiovascular complications. In this study we were looking for potent compounds with moderate selectivity for cox-2. So, four analogues of 4, 5-diaryl-2-(2-alkylthio-5-imidazolyl) imidazole derivatives were synthesized and their anti-inflammatory and anti-nociceptive ac...
