“…The mechanistic aspects of b-boryl and b-silyl elimination occuring in these processes based on DFT calculations have been recently reported. 3a,b The reaction, well-recognized as a new catalytic route for activation of QC-H bond of olefins and QC-E bond of vinylmetalloid derivatives (where E = Si, B, Ge and others) with ethylene evolution has been recently extended to the activation of RC-H 4,5 (for E = Si, Ge), QC aryl -H (E = Si) 6 as well as -OH bonds of alcohols 7 and silanols, 8 particularly by vinylsilanes (for review see ref. 9).…”
