The gold rush: A cationic gold(I) complex, supported by a CAAC ligand, promotes the intramolecular addition of NH or NMe bonds (from ammonium salts or tertiary amines, respectively) to carbon–carbon triple bonds; the same complex allows for the isolation of vinylgold intermediates. X=(C6F5)4B. CAAC=cyclic (alkyl)(amino)carbene.
淘金热:由 CAAC 配体支持的阳离子金 (I) 络合物促进 N H 或 N Me 键(分别来自铵盐或叔胺)与碳-碳三键的分子内加成;相同的复合物允许分离乙烯基金中间体。X=(C 6 F 5 ) 4 B.CAAC=环状(烷基)(氨基)卡宾。
