Pd（0）-Catalyzed Tandem One-Pot Reaction of Biphenyl Ketones/Aldehydes to the Corresponding Di-substituted Aryl Olefins

Synthesis of di-substituted aryl olefins via a Pd（0）-catalyzed cross-coupling reaction of biphenyl ketones/alde- hydes, tosylhydrazide, and aryl bromides （or benzyl halides） was developed. This methodology was achieved by one-pot two-step reactions involving the preparation of N-tosylhydrazones by r...

description Synthesis of di-substituted aryl olefins via a Pd（0）-catalyzed cross-coupling reaction of biphenyl ketones/alde- hydes, tosylhydrazide, and aryl bromides （or benzyl halides） was developed. This methodology was achieved by one-pot two-step reactions involving the preparation of N-tosylhydrazones by reacting tosylhydrazide with biphenyl ketones/aldehydes, followed by coupling with aryl bromides （or benzyl halides） in the presence of Pd（PPh3）4 and lithium t-butoxide to produce various di-substituted aryl olefins in moderate to good yields.
