合成了乙二醛双腙1和吡啶基腙2b，并研究了它们作为配体在卤代芳烃和烯烃的Mizoroki-Heck偶联反应中的作用。我们发现PdCl_2（MeCN）_2/腙配体1 e是一个无膦的高效催化体系，对多种底物都能以良好的产率生成Mizoroki-Heck偶联产物。
Glyoxal bishydrazones 1 and pyridyl-hydrazone 2b were prepared and examined as a ligand for the Mizoroki-Heck cross-coupling reaction of aryl halides and olefin. We found that PdCl2(MeCN)2/hydrazone ligand 1e was a phosphine-free efficient catalyst system for a variety of substrates to produce the Mizoroki-Heck coupling products in good yields.
