denitrogenative and desulfinative addition of arylsulfonyl hydrazides with nitriles has been successfully achieved under mild conditions. This transformation is a new method for the addition reaction to nitriles with arylsulfonyl hydrazides as arylating agent, thus providing an alternative synthesis of aryl ketones. The reported addition reaction is tolerant to many common functional groups, and works

The first example of electrochemical deoxygenative C2 arylation of quinoline N-oxides using sulfonyl hydrazines was demonstrated in this work. By employing both anodicoxidation and cathodicreduction, a variety of 2-arylquinolines were synthesized under metal catalyst-, exogenous-oxidant-, and exogenous-reductant-free conditions.

In the presence of a Pd(II)/P-ligand catalytic system, decarboxylative alkynylation of alkynyl carboxylicacids and arylsulfonyl hydrazides by desulfinative coupling could provide aryl alkynes in satisfactory yields by either judiciously selecting palladium catalysts or modulating phosphine ligands under mild conditions. The reported coupling reactions are very practical as they do not require the
