Golden tendencies: The title reaction for synthesizing cyclopentenone derivatives utilizes a gold complex and 8‐methylquinoline oxide as the catalyst system (see scheme; IPr=1,3‐bis(diisopropylphenyl)imidazol‐2‐ylidene). Such products are not attainable using diazocarbonyl reagents, as the gold carbenoids tend to react with CH bonds.
黄金趋势:合成环戊烯酮衍生物的标题反应利用金络合物和8-甲基喹啉氧化物作为催化剂体系(参见方案; IPr = 1,3-双(二异丙基苯基)咪唑-2-亚基)。这样的产品不能达到使用diazocarbonyl试剂,作为金卡宾倾向于与下反应 H键。
