Synthesis of Dithioacetals through Iodine-Promoted Insertion Reactions of Vinylsilane to Disulfides and its Application to Diselenoacetalization

Abstract

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 diaryl diselenide to afford the corresponding diselenoacetal derivative.

Key words

disulfide - vinylsilane - iodide molecules - insertion reaction - dithioacetal - diselenoacetal

• 18 One reviewer pointed out the use of a substituted vinyltrimethylsilane as methyl-substituted vinyltrimethylsilane to clarify the regioselectivity of the insertion reaction to a disulfide. However, the present dithioacetalization is limited to the use of unsubstituted vinyltrimethylsilane, and the reactions with substituted vinyltrimethylsilanes and substituted styrene derivatives did not proceed.
