Abstract

The abstraction reactions CH3 + H2 --+ CH4 + H, SiH3 + H2 --+ SiH4 + H, NH2 + H2 --+ NH3 + H, and PH2 + H2--+ PH3 + H have been studied with a variety of methods, including MCSCF, POL-CI, UMP2, and UMP3. In agreement with the observed thermochemistry, abstraction by methyl radical is found to proceed more easily than by silyl, and the reverse of the last reaction occurs with a very small ( ~ 5.6 kcal/mol) barrier. POL-CI appears to be a consistently reliable approach for this type of reaction.
