摘要：

Continuous-wave CO2 laser-photosensitized (SF6) decomposition of 4-silaspiro[3,3]heptane is dominated by the transient formation and polymerization of 2-silaallene. The first experimental evidence for 2-silaallene has been achieved via scavenging with alcohols ROH (R = CH3, CF3CH2) to afford dialkoxy(dimethyl)silanes, (RO)(2)Si(CH3)(2). ESCA analysis of the polymer demonstrates SiC2 stoichiometry and indicates the incorporation of oxygen, which may be explained by reaction of the residual Si=C bonds with air.
