Visible-light-driven multicomponent reactions of acyl ketene dithioacetal sulfonium salts with amines and CS 2 or CO 2 to access S -acyl ketene dithioacetal dithiocarbamates and O -acyl ketene dithioacetal carbamates

A visible-light-induced three-component reaction of acyl ketene dithioacetal sulfonium salts with secondaryamines and CS 2 or CO 2 was developed, providing a green route to S -substitued dithiocarbamates and O -substituted carbamates.
