Laser-powered homogeneous pyrolysis of 4-silaspiro[3,3]heptane. A source for 2-silaallene and its polymer

Continuous-wave CO 2 laser-photosensitized (SF 6) 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  CH 3, CF 3CH 2) to afford di...

Description
Summary:Continuous-wave CO 2 laser-photosensitized (SF 6) 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  CH 3, CF 3CH 2) to afford dialkoxy(dimethyl)silanes, (RO) 2Si(CH 3) 2. ESCA analysis of the polymer demonstrates SiC 2 stoichiometry and indicates the incorporation of oxygen, which may be explained by reaction of the residual Si  C bonds with air.
