Abstract

The combinations and disproportionations of the CH3 and 2-propyl (iP) radicals with the 1,1,2-trimethylallyl (TMA) radical have been studied in the gas phase in the temperature interval of 389-451 K and 490-540 K, respectively. For the ratios of the terminal (t) and non-terminal (n) combinations of the CH3 and iP radicals with the TMA radical, values of 1.9±0.1 and 2.84±±0.10 were obtained, respectively. The ratios of the tt and tn and nn to tn combinations of the TMA radical were 1.59 and 0.46, respectively. The disproportionation-combination rations were Δ(CH3, TMA)=0.022±±0.012 and Δ(iP, TMA)=0.026±0.011.
