Free-radical induced addition reactions of oct-1-ene and the following compounds containing activated methylene or methine groups have been effected: diethyl butylmalonate, di-isopropyl malonate, diethyl acetylmalonate, diethyl cyanomalonate, triethoxycarbonylmethane, 1,1,2-triethoxycarbonylethane, ethyl diacetylacetate, and ethyl phenylacetate. The radical-induced additions of ethyl acetoacetate and
自由基诱导了辛-1-烯与以下含有活化的亚甲基或次甲基的化合物的加成反应:丙二酸二丁酯,丙二酸二异丙酯,乙酰丙二酸二乙酯,氰基丙二酸二乙酯,三乙氧基羰基甲烷,1,1,2-三乙氧基羰基乙烷,二乙酰乙酸乙酯和苯乙酸乙酯。已对自由基诱导的乙酰乙酸乙酯和丙二酸二乙酯的自由基诱导加成反应以及乙酰丙酮与辛-1-烯的过氧化物和光诱导反应进行了重新研究。讨论了这些反应的合成和理论后果,以及某些附录的烯醇化程度相对于产品性质的可能意义。
