摘要

Abstract Compounds of the type CH 2 CHCH 2 MR 3 and E-PhCH CHMR 3 (M Si, Ge, Sn, Pb) were allowed to react with a series of heteroatom-centered radicals (PhY·, Y= S, Se, Te, derived from PhYYPh) and carbon-centered radicals ((CH 3) 2 CH· derived from (CH 3) 2 CHHgCl). We report that alkenylplumbanes and, under forcing conditions, alkenylgermanes undergo SH 2 or SH 2′ substitution of the metal by chain mechanism ...
