The infrared spectra of gaseous and solid chloromethyl methyl silane, CICH2SiH2CH3, and chloromethyl methyl difluorosilane, CICH2SiF2CH3, were recorded. Additionally, the variable temperature infrared spectra of the sample dissolved in liquid krypton and/or xenon were obtained. Both the trans and gauche conformers are present in the fluid phases but only the trans conformer is present in the solid for both molecules. The enthalpy difference between the two conformers for chloromethyl methyl silane was determined to be 180 ± 15 cm-1 (2.16 ± 0.18 kJ./mol) and for chloromethyl methyl difluorosilane 236 ± 15 cm-1 (2.82 ± 0.17 kJ/mol) in xenon with the gauche conformers more stable for both molecules. The enthalpy value for the silane in krypton is 181 ± 18 cm-1 (2.16 ± 0.09 kJ/mol). Ab initio calculations were carried out at the RHF/6-31G* and MP2/6-31G* levels for both molecules from which structural parameters and conformational stabilities were determined.

Various alkali metal halides were found to catalyze the Si-H/Si-Cl redistribution reaction in different polar solvents efficiently. The scope of silane substrate was studied using KF as catalyst and 18-crown-6 as cocatalyst in DMI. The alkali metal halides catalyzed redistribution system provides a useful method to prepare hydrochlorosilanes more facilely. A possible mechanism was proposed to explain the process.

The synthesis and reaction behavior of pentacoordinate hydrochlorosilanes LCH2SiRHCl (L- 2-piperidonyl ligand, R = Me, Ph, Bn) are described. The intramolecular O-Si and N-Si coordination is discussed on the basis of the NMR data. The strength
