The order of reactivity towards SH2 attack by tributyltin 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-CNC6H4S > PhS > p-MeC6H4S > MeS . The mechanism of the reaction of chloromethyl phenyl sulfide with alkoxides is discussed.
通过竞争实验发现,在四种不同的分子环境(RCO2CH2X、RCH2OCH2X、XCH2CO2Et 和 RCH2X)中,三丁基锡自由基对各种基团 X 的 SH2 攻击的反应性顺序为 Br > PhSe > Cl > p-CNC6H4S > PhS > p-MeC6H4S > MeS。讨论了氯甲基苯基硫醚与烷氧基化合物的反应机理。
