摘要
A series of novel and previously published silicon dichlorides, R2SiCl2 (R = benzyl, fluorenyl, p-tolyl p-n-butyl, p-biphenyl, m-tolyl, o-tolyl, 2,4-xylyl, 2,6-xylyl, p-biphenyl, 1-naphthyl, 9-anthracenyl), were synthesized and characterized using H-1-, C-13- and Si-29 NMR spectroscopy. Effects of substituent bulk on both experimental and calculated Si-29 NMR shifts are compared between reported silicon dichlorides species and novel dichlorides herein. In addition, single crystal X-ray diffraction was employed to elucidate the molecular structure of all solid diorgano silicon dichlorides. These compounds display non-covalent intermolecular interactions in the form of edge to face, - stacking, and CH3<bold> interactions</bold>. Dependency of substituent type on the nature of interactions present will be highlighted and discussed.
