The stereochemistry of the reactions of 1-phenylsulfinylethyl radical (1r) and 1-pehnylsulfinyl-2,2,2-trifluoroethyl radical (2r) with allylstannanes has been examined. Preferential formation of products of opposite relative configuration has been observed. Conformational analysis of the radical intermediates (AM1 calculations) allows to rationalize the results.
已经研究了1-苯基亚磺酰基乙基(1r)和1-苯基亚磺酰基-2,2,2-三氟乙基(2r)与烯丙基锡烷的反应的立体化学。已经观察到相反的相对构型的产物的优选形成。自由基中间体的构象分析(AM1计算)可以使结果合理化。
