Significance

Immersion of the gold surface in a solution of phosphine 1 in EtOH afforded [Au]-SMAP 2. [Au]-SMAP 2 was treated with a solution of [RhCl(C2H4)2]2 in benzene to give [Au]-SMAP-Rh 3. ICP-MS measurement of 3 revealed that rhodium was incorporated at a concentration of 0.63 nmol/cm². [Au]-SMAP-Rh 3 was found to promote the dehydrogenative silylation of primary alcohols 4 to afford the corresponding silyl ether 5a-d with high TON up to 68,000 (eq. 1).
