Described herein is an iodide-promoted insertion reaction of vinyltrimethylsilane into diaryl or dialkyl disulfides in the presence of iodine/KF leading to the production of a 1,1′-adduct, a dithioacetal derivative. This method also accomplishes insertion into a diaryldiselenide to afford the corresponding diselenoacetal derivative.

Catalyst-controlled divergent reactions of thiophenols with alkenes bearing heteroatoms have been developed. Markovnikov-type hydrothiolation products and thioacetals were synthesized selectively by switching copper catalysts.
