oro-1-aryl-2-(2′,2′-diarylvinyl)allyl]palladium(II) complexes has been developed from the reaction of arylvinylcyclopropenes with a Pd(II) complex along with a novel dehydrogenative rearrangement of arylvinylcyclopropenes via di-μ-chlorobis[π-1-chloro-1-aryl-2-(2′,2′-diarylvinyl)allyl]palladium(II) complexes to produce 7H-benzo[c]fluorene derivatives in good yields under mild conditions. A stoichiometric
通过芳基乙烯基环丙烯的反应,开发了一种新的合成方法,用于制备二-μ-氯双[π-1-氯-1-芳基-2-(2',2'-二芳基乙烯基)烯丙基]钯(II)配合物Pd(II)配合物,以及经由二-μ-氯双[π-1-氯-1-芳基-2-(2',2'-二芳基乙烯基)烯丙基]钯(II)配合物对芳基乙烯基环丙烯进行的新型脱氢重排在温和条件下以高收率生产7 H-苯并[ c ]芴衍生物。化学计算量的银盐或催化量的强布朗斯台德酸HOTf可能是这种有趣的脱氢重排的促进剂或催化剂。
