Visible-light-induced dehydrogenative sulfonylation of tertiary amines under transition-metal- and photocatalyst-free conditions

Abstract

An efficient dehydrogenative sulfonylation of tertiary amines with thiosulfonates enabled by visible-light irradiation is developed. This protocol allows for the construction of a variety of cyclic and acyclic β-sulfonyl enamines under transition-metal-free, external oxidant-free, photocatalyst-free and mild reaction conditions.
