of substituted benzyldimethylsilanes (I) and phenyltetramethyldisilanes (II) are reported. 29SiH and 13CH coupling constants are shown to be correlated by Hammett σ constants. The data are discussed in terms of mechanisms of transmission of substituent effects across C—Si and Si—Si bonds. A good Hammettcorrelation is also found of J(13CH) for the benzylic protons of a series of substituted toluenes

Dehydrogenative dimerization of benzylmethylsilanes under iridium catalysis via site-selective sequential silylations of a C(sp3)–H bond of the methyl group and ortho C(sp2)–H bond of the benzyl group is described. Silicon-containing heterocycles were obtained in a single step from readily available functionalized benzylmethylsilanes.
