Electrochemical Coupling of Arylsulfonyl Hydrazides and Tertiary Amines for the Synthesis of β-Amidovinyl Sulfones
Kim, Han-Sung,Lee, Sunwoo
, p. 6951 - 6955 (2019)
The reaction of arylsulfonyl hydrazides with tertiary amines provided β-amidovinyl sulfones in good yields under mild electrochemical conditions. The reactions were carried out using an acid, in a solution of nBu4NBF4 in dimethyl sulfoxide in undivided cells with graphite-platinum electrodes under a constant current. The arylsulfonyl hydrazides and tertiary amines were activated via a radical process by electrochemical oxidation and reacted to give the desired β-amidovinyl sulfones.

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.

The novel synthesis of β-arylsulfonyl enamines has been achieved by visible light-mediated dehydrogenative arylsulfonylation of tertiary aliphatic amines with arylsulfonyl chlorides in moderate yield. This journal is
Nucleophilic addition of highly hindered amines to electron-deficient acetylenes
Cossu, Sergio,De Lucchi, Ottorino,Durr, Richard
, p. 4597 - 4601 (2007/10/03)
Even the most highly hindered amines such as diisopropylamine, isopropyl-t-butylamine, 2,2,6,6-tetramethylpiperidine, 4-oxo-2,2,6,6-tetramethyl piperidine and hexamethyldisilazane react with electron-deficient alkynes to give the Michael addition products
