A dirhodium-catalyzed, ?-selective C-H amination of organosilicon compounds has been developed. Primary C(sp3)-H bonds of silylethyl groups and secondary C(sp3)-H bonds of silacycloalkanes can be selectively converted to C-N bonds at the ?-position of the silicon atoms. The experimental data and theoretical calculations indicate that the strong s-donor ability of the carbon-silicon bonds is responsible for the ?-selectivity. Kinetic isotope effects clearly demonstrate that the C-H bond cleavage step is not turnover-limiting, but selectivity-determining.
