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

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

A novel and highly efficient cascadesynthesis of sulfonated quinoline dione derivatives from N-(2-cyanoaryl) methylacrylamides and sulfonylhydrazides in good yields is described. The reaction proceeds through radicaladdition, cyclization, and imine hydrolysis, in which one new C–C bond and one CO bond were formed.
