Rate constants for the gas phase reactions of CC1 generated by the flash photolysis of CHBrzCl with a series of silanes have been obtained by kinetic absorption spectroscopy. In general, the rate constants arc very high, and range fmm (4 8 2 0.5) X 10' (SIHH~) to (6-4 r 0.34) % IO9 for SitHe. CC1 do
