Golden aryne? Gold aryne complexes are inferred as transition states in dualgold‐catalyzed cyclizations of cis‐enediynes (see scheme; DCE=1,2‐dichloroethane). They are better described as ortho‐aurophenyl cations, which react with weak nucleophiles and undergo facile intramolecular insertions into C(sp3)H bonds. Indanes, fused heteroarenes, and phenol derivatives are readily prepared using this method
金亚宁?金芳炔配合物被推断为双金催化的顺式烯二炔环化中的过渡态(参见方案;DCE=1,2-二氯乙烷)。它们被更好地描述为邻-金苯基阳离子,它与弱亲核试剂反应并进行分子内插入 C(sp 3 ) H 键。使用这种方法很容易制备茚满、稠合杂芳烃和苯酚衍生物。
