Laser-powered homogeneous pyrolysis of 4-silaspiro[3,3]heptane. A source for 2-silaallene and its polymer
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-sihiallene has been achieved via scavenging with alcohols ROH (R = CH3. CF3CH2) to afford dialkoxy(dimethyl)silanes. (RO)2Si(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.

Shock-induced kinetics of the disilane decomposition and silylene reactions with trimethylsilane and butadiene
The homogeneous gas-phase decomposition kinetics of disilane have been studied by the comparative rate, single-pulse shock-tube technique in the 850-1000 K (2300-2700 torr) ranges. Two primary dissociation processes occur, Si2H6-i SiH4/su
