摘要：

Various aerosils surface modified with silane reagents were prepared and investigated by Si-29 solid state NMR spectroscopy. The mode of bonding onto the silanol surface (mono- or divalent) can be specified by comparison with chemical shifts from solution. A detailed analysis also leads to the detection of products formed via hydrosilylation reactions. A rough quantification of the surface loading can be obtained by a signal deconvolution process of the silanol resonances on the Aerosil surface.
