Thirteen chlorosilanes have been prepared by the reaction between phosphorus pentachloride and the corresponding silanes. Yields were between 78·1 and 96·4%. Silicon atoms bearing chlorine or oxygen atoms were less reactive than other silanes. Phenyldichlorosilane failed to react.
The effects of the alkoxy side chain on the conformation of oligosilane have been studied for perpentoxypentasilane. The UV-absorption maxima shifted extremely to a shorter wavelength than that of peralkyloligosilane. Molecular dynamics and ab initio MO calculations showed that the excitation energy of the twisted structure for peroxyloligosilane (a model of perpentoxypentasilane) was smaller than
