Direct ESR Evidence for SH2 Type Reaction of a Methyl Radical with Methylsilane and Methylgermane in a Low Temperature Solid: a Deuterium Labelling Study
(2005) In Chemical Physics Letters 410(1-3). p.1-5- Abstract
- The first ESR spectroscopic evidence of a bimolecular homolytic substitution (SH2) reaction in a 77 K solid phase was presented, where radicals were substituted for the CH3 group of methylsilane and methylgermane (CH3XD3, X = Si, Ge). The radicals were generated by in situ UV-photolysis of CD3I in the solid CH3XD3 in an ESR cavity at 77 K. Using the selectively deuterium labeled compounds, it was demonstrated that the SH2 reaction proceeded over a competitive H atom abstraction reaction with a large H/D isotope effect. Ab initio and density functional theory calculations complement the experimental results.
