Methylchlorooligosilanes as products of the basecatalysed disproportionation of various methylchlorodisilanes

The methylchlorodisilanes SiCl₂Me-SiCl₂Me (1), SiCl₂Me-SiClMe₂ (2) and SiClMe₂-SiClMe₂ (3) disproportionate in the presence of a basic catalyst into methylchloromonosilanes and various methylchlorooligosilanes. Oligosilanes involving up to seven silicon atoms were identified by means of ²⁹Si-, ¹³C-¹H-NMR and GC-MS measurements. Formation of methylchlorooligosilanes is thought to take place via silylene intermediates.
