Gold(I)-phosphine complexes are readily encapsulated by a tetrahedral supramolecular host (Ga(4)L(6)). We have investigated the catalytic activity of the resulting complexes for the intramolecular hydroalkoxylation of allenes. The catalytic activity of Me(3)PAuBr was increased 8-fold by encapsulation, as determined by initial rate kinetics, and we observed up to 67 catalytic turnovers by Me(3)PAu(+) encapsulated in Ga(4)L(6).
金（I）-膦配合物很容易被四面体超分子主体（Ga(4)L(6)）包裹。我们研究了所得配合物对丙二烯的分子内烷氧基化反应的催化活性。通过初始速率动力学确定，Me(3)PAuBr 的催化活性通过包裹提高了 8 倍，Me(3)PAu(+)包裹在 Ga(4)L(6)中观察到高达 67 个催化循环。
