SO42− ions as a nucleophilic reagent: straightforward electrochemical access to organosulfates

Abstract

An electrooxidation direct difunctionalization of alkynes with sulfonyl hydrazides has been developed for the construction of sulfonyl alkenyl sulfates in the absence of metal catalysts and a stoichiometric amount of oxidants. Notably, it is the first example to verify that SO₄²⁻ ions can act as a nucleophilic reagent for the preparation of organosulfates.
