title: Regioselective hydrothiolation of alkynes by sulfonyl hydrazides using organic ionic base-Brønsted acid.
abstract: A practical and novel approach has been developed for the synthesis of vinyl sulfides by the reaction of sulfonyl hydrazides with aryl/heteroarylacetylenes using a DBU-based ionic liquid. The system offers a new sulfur source for hydrothiolation and is endowed with green credentials.
