Significance

A set of photochemical conditions are developed for synthesizing selenoesters and telluroesters, with a visible-light induced siloxycarbene intermediate suggested to react with electrophilic chalcogen reagents. The reaction exhibits a wide substrate scope.

Comment

Through a series of control experiments, a plausible reaction mechanism is proposed, involving a photo-induced isomerization of an acylsilane, which undergoes nucleophilic attack on electrophilic selenium or tellurium reagents, prior to desilylation.
