The first palladium-catalyzedSuzukicross-coupling of N'-tosyl arylhydrazines with various organoboron reagents has been developed for the preparation of biaryl compounds in high yields. N'-Tosyl arylhydrazine as a readily available and stable electrophile also demonstrated its generality in a number of coupling reactions.

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.
