Pyrolysis of hexamethyldisiloxane (HMDS) and its copyrolysis with chlorotrimethylsilane and tetrachlorosilane were studied. Based on the data of GLC analysis and on the mass spectrum of the condensate obtained after the pyrolysis of HMDS, it was concluded that HMDS acts as a source of dimethylsilanone. The results of the copyrolysis of HMDS with chlorotrimethylsilane used as a trapping reagent indicate that the dimethylsilanone generated from HMDS can be inserted into the Si-Cl and Si-O bonds. In the copyrolysis of HMDS with tetrachlorosilane serving as a trapping reagent for dimethylsilanone, both dimethylsilanone and dichlorosilanone are generated.

GAS-PHASE REACTIONS OF ORGANOSILICON HYDRIDES WITH (BENZYLOXY)TRICHLOROSILANE
Dichlorosilanone generated by the pyrolysis of (benzyloxy)trichlorosilane undergoes an insertion reaction at the Si-H bond in organosilicon hydrides with the formation of new hydride organosiloxanes.It was shown that gas-phase reactions of organosilicon hydrides with (benzyloxy)trichlorosilane go by a radical chain mechanism.
