• electrophile trapping with the sulfone corresponds approximately to the rate of hydrogen atom transfer from (TMS)3SiH. Attempted reaction with methyl vinyl ketone, N,N-dimethylacrylamide and methyl propiolate gave rearranged-reduced azacycle 8 in modest yields, as well as small quantities of hydrosilylated
