Palladium-catalyzed Suzuki cross-coupling of N′-tosyl arylhydrazines

Abstract

The first palladium-catalyzed Suzuki cross-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.
