摘要：

Gold(I)-phosphine complexes are readily encapsulated by a tetrahedral supramolecular host (Ga4L6). We have investigated the catalytic activity of the resulting complexes for the intramolecular hydroalkoxylation of allenes. The catalytic activity of Me3PAuBr was increased 8-fold by encapsulation, as determined by initial rate kinetics, and we observed up to 67 catalytic turnovers by Me3PAu+ encapsulated in Ga4L6.
