摘要：

Efficient isomerization of Si(C2H5)H2+ to the thermodynamically more stable Si(CH3)2H+ ion in the gas phase by using Fourier transform mass spectrometry (FTMS) is described. This isomerization is induced by collisional activation with structures of the SiC2H7+ ions probed by specific ion molecule reactions with ethene-d4 and methanol. The isomerization is proposed to proceed by a concerted 1,2-hydrogen/1,2-methyl migration (dyotropic rearrangement).
