英文摘要	direct synthesis of 1,1-disubstitued 1,3-butadienes has been efficiently realized from the cross-coupling of cyclopropylmethyl n-tosylhydrazones with aromatic bromides by means of pdcl2(mecn)(2) as catalyst. 1,1,4-trisubstitued 1,3-butadiene derivatives were obtained in up to 70% yields through a one-pot procedure catalyzed by pd(oac)(2) in the presence of excessive amount of aromatic bromides. the present methodology provides an easy and efficient route to multisubstituted 1,3-butadienes.
