Abstract
The carbanions produced by deprotonation at the carbon of methylthio group of 2-methylthio-2-phenyl-1,3-dithiane and of 4,6-dithia-5-methylthio-5-phenylnonane undergo the Sommelet type rearrangement to give intermediary thiolate anions which, on further deprotonation and the subsequent trapping with alkyl iodides, afford 2-alkyl-2-[2-(alkylthiomethyl)phenyl]-1,3-dithiane and alkyl 2-(alkylthiomethyl)phenyl ketone dipropyl dithioacetals, respectively.
