Relative Reactivities of Various Sulfides, Selenides and Halides Towards SH2 Attack by Tributylgermyl Radicals

Abstract

The order of reactivity towards SH2 attack by tributylgermyl radicals on various groups X in four different molecular environments (RCO2CH2X, RCH2OCH2X, XCH2CO2Et and RCH2X) has been found by competition experiments to be Br > PhSe > Cl > p-NCC6H4S > PhS . The relative rates of addition of Bu3Ge? To three classes of olefins have also been determined.
