p-Tolylsulfinyl Amides: Reagents for Facile Electrophilic Functionalization of Olefins

Krasnova, Larissa B.,Yudin, Andrei K.

, p. 2584 - 2587 (2004)

A variety of olefins were found to react with sulfinyl amides in the presence of POCl3 to give β-chlorosulfides and β-hydroxysulfides in good yields. In the absence of nucleophiles, p-tolylsulfinyl amides were found to react with olefins with the formation of allylsulfoxides.
