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
