nitriles to N-phenyl amides has been achieved through a novel intermolecular phenyl transfer reaction from phenyl hydrazides and N-addition to nitriles in the presence of PIFA under mild and solvent-free conditions. This cross-coupling reaction includes the oxidative cleavage of sp2 C–N bonds of phenyl hydrazides to form a phenyl radical and the subsequent N-addition to cyanos to form new sp2 C–N bonds

A novel procedure for the preparation of biaryl compounds by Pd-catalyzed homocoupling of N′-tosyl arylhydrazine has been described. N′-Tosyl arylhydrazine, as a readily available and stable coupling partner, demonstrated its generality in the homocoupling reactions. The scope of the reaction and possible mechanism have also been investigated.
