Abstract

Abstract Diaryl Diselenides react with CO (5–100 atm) at 100-200 C during 1–4 h in the presence of Co 2 (CO) 8 to give the corresponding aryl selenocarboxylic acid esters in 21– 96% yields. Similar treatment of diphenyl ditelluride gives the telluro analogues in lower yields. Didodecyl diselenide also gives the corresponding seleno ester, while esters were not produced from dibenzyl diselenide and didodecyl ditelluride. Under milder conditions ( ...
