A photcatalyst-free photoredox synthesis of diaryl selenides has been developed by coupling reaction of diselenides with aryldiazo sulfones. The reaction was accelerated under visible light irradiation without using a photocatalyst or photosensitizer. This approach facilitates the synthesis of diaryl selendes with a wide range of functional group tolerance.

Aryl-heteroatom bonds (C-Het) are almost ubiquitously present in chemical molecules. However, methods for diverse C-Het bond formations from a simple substrate are limited. Herein, we report a convenient and efficient C-S bond transformation of aryl sulfoniums to various C-Het bonds (C-O, C-S, C-Sn, C-Si, C-Se) in the absence of any transition-metal catalyst. These reactions proceeded in mild conditions with a wide substrate scope.
Selenoxides as catalysts for epoxidation and Baeyer-Villiger oxidation with hydrogen peroxide

Aryl benzyl selenoxides are catalysts for the epoxidation of various olefinic substrates and the Baeyer-Villiger oxidation of aldehydes and ketones with H2O2 in CH2Cl2 at 2.5 mol% catalyst. Benzyl 3,5-bis(trifluoromethyl)phenyl selenoxide (4) was the most effective catalyst while 2-(dimethylamino)phenyl benzyl selenoxide was the least. Mono-, di-, and trisubstituted alkenes were epoxidized and adamantanone, cyclohexanone, and 3,4,5-trimethoxybenzaldehyde underwent Baeyer-Villiger oxidation using 4 and H2O2. Competition studies showed that epoxidation reactions were faster than Baeyer-Villiger oxidations although the selectivity varied only from 1.3:1 to 4.6:1. Georg Thieme Verlag Stuttgart.

This article describes the first attempt to synthesize selenides and selenol esters prepared from the reaction of 1-benzyl or 1-acyl-selenophenylmethaniminium halides and organic halides under liquid-liquid phase-transfer conditions. This method also can
