Raman and infrared spectra, quantum chemical calculations, conformations and spectral assignments of 1-chloro-1-methyl-1-silacyclohexane

A 1,1-disubstituted silacyclohexane, 1-chloro-1-methyl-1-silacyclohexane, C5H10SiClCH3, was synthesized and studied by infrared and Raman spectroscopy. The infrared spectra of the vapor and liquid were recorded at ambient temperature and the solid sample investigated at 78 K. Negligible spectral changes ocurred at 78 K compared with the fluid state, but after annealing to ca. 165 K an apparent crystal was formed. Raman spectra of the liquid were recorded at 293 K and depolarization data obtained. Additional Raman spectra were recorded at various temperatures between 293 and 143 K. A supercooled liquid appeared after slow cooling, but an amorphous solid phase was observed after shock freezing to 78 K. After annealing, a plastic phase was observed and an anisotropic crystal appeared after further annealing. In the crystalline phase spectral shifts and some vanishing bands were observed and only the a (Cl) conformer remained. The compound exists in two conformers, equatorial (Cl) (e) and axial (Cl)(a) in the liquid, amorphous and plastic phases, but only the a-conformer was present in the crystal. The experimental results suggest that the a-conformer has 1.5 ± 0.5 kJ mol-1 lower enthalpy than e in the liquid.

A Convenient Synthetic Route to Methylated Silacyclohexanes

The von Braun degradation of substituted piperidines is a general and economical route to a variety of substituted primary and secondary α,ω-dibromopentanes.Grignard ring closure procedures have been carried out with seven different dibromopentanes in moderate to good yields.Ring closures with MeClSiCl2 lead to product mixtures which are appreciably enriched in one isomer, affording a convenient entry into a variety of derivatives which can be used for stereochemical studies.Assignment of structures based on 1H NMR and mass spectral fragmentation patterns is discussed
