Phenylmethyldifluorosilane reacts with aldehydes in the presence of a fluor
ide salt and a catalytic amount of a cationic rhodium complex, [Rh(cod)(CH3
CN)(2)]BF4, affording the corresponding phenylated alcohols in good yield.
The reaction mechanism involves the transmetalation between a fluorine-coor
dinated silicate and a rhodium complex to generate a phenylrhodium species.
