摘要

The reaction of ground-state boron atoms, B(~2P_j), with dimethylacetylene, CH_3CCCH_3 (X~1A_(1g)), was studied at a collision energy of 17.9 kJ mol~(-1) using the crossed molecular beam approach. It was found that the reaction follows indirect scattering dynamics. B(~2P_j) attacks the carbon-carbon triple bond of the dimethylacetylene molecule to form a cyclic BC_4H_6 intermediate that undergoes hydrogen transfer from the methyl group to the boron atom. This complex then rotates around the A/B axis and fragments to atomic hydrogen plus a cyclic BC_4H_5 isomer, 1,2-dimethylene-3-bora-cyclopropane, via a tight transition state.
