The cationic gold phosphine complex [PCy2(o‐biphenyl)}Au(NCMe)]+SbF6− (Cy=cyclohexyl) catalyzes the intermolecular, anti‐Markovnikov hydroamination reaction of monosubstituted and cis‐ and trans‐disubstituted alkylidenecyclopropanes (ACPs) with imidazolidin‐2‐ones and other nucleophiles. This reaction forms 1‐cyclopropyl alkylamine derivatives in high yield and with high regio‐ and diastereoselectivity
所述阳离子金膦络合物[PCY 2(ø -联苯)}金(NCMe)] +的SbF 6 -(CY =环己基)催化的分子间,单取代和反马氏加氢胺化反应的顺式-和反式二取代的alkylidenecyclopropanes(ACP的)与咪唑啉丁-2-酮和其他亲核试剂一起使用。该反应以高收率,高区域选择性和非对映选择性形成1-环丙基烷基胺衍生物。金π-ACP配合物的NMR光谱分析和对照实验表明,ACP内部烯烃碳原子的sp杂合可控制ACP加氢胺化反应的区域化学反应。
