Irradiation using a low pressure mercury lamp (lambda =ca. 250 nm) of argon matrices containing ca. 1% (Me2Si)(6) and ca. 20% ethylene oxide (C2H4O) or nitrous oxide (N2O) for a period of ca. 20 h leads to the formation of the cyclic compound (Me2SiO)(6). This has a 12-membered ring with alternating Si and O atoms. It is identified by comparison of its infrared spectrum with a spectrum of an authentic sample. The reaction appears to proceed by stepwise insertion of O atoms into Si-Si bonds.

Abstract

Irradiation using a low pressure mercury lamp (lambda =ca. 250 nm) of argon matrices containing ca. 1% (Me2Si)(6) and ca. 20% ethylene oxide (C2H4O) or nitrous oxide (N2O) for a period of ca. 20 h leads to the formation of the cyclic compound (Me2SiO)(6). This has a 12-membered ring with alternating Si and O atoms. It is identified by comparison of its infrared spectrum with a spectrum of an authentic sample. The reaction appears to proceed by stepwise insertion of O atoms into Si-Si bonds.
