Metal-Free Vinyl C?H Sulfenylation/Alkyl Thiolation of KeteneDithioacetals for the Synthesis of Polythiolated Alkenes

摘要

The sulfenylation of the vinyl C?H bond inketene dithioacetals leading to the synthesis of polythiolatedalkenes is achieved via the promotion of molecular iodine. Inaddition, alkyl thiols also exhibit tolerance to the C?H bondelaboration reaction for the synthesis of correspondingalkylthiolated ketene dithioacetals.
