Abstract: Rate constants for hydrogen atom abstraction from n-Bu3GeH (kGeH) by Me3SiCH2'(lo), Me3SiCH2CH2'(2*), and Me3SiCH2CH2CH,'(3') and from n-Bu3SnH (pH) by 1'and 3'have been determined at ambient temperatures. The order of decreasing radical reactivity is 1'> n-alkyl> 3'> 2'. However, for bromine abstraction from the parent bromides by n-Bu3Sn'and n-Bu3Ge', the order of decreasing reactivity is 1-Br> 2-Br> 3-Br-n-alkyl ...
