and for a long time gold was even thought of as "catalytically dead". This is clearly not the case for cationic phosphanegold(I) complexes (see reaction below), which can catalyze the addition of alcohols to alkynes with turnover frequencies up to 1.5 s-1 and total turnover numbers up to 105 ! R=H, alkyl, Ph, CH2 OH.
金络合物在均相催化中几乎是未知的,并且很长一段时间以来,金甚至被认为是“催化死亡”的。阳离子膦金(I)配合物显然不是这种情况(请参见下面的反应),它可以催化将醇类添加到炔烃中,其周转频率高达1.5 s -1,总周转数高达10 5!R = H,烷基,Ph,CH 2 OH。
