Electrolytic reduction of dichloromethylphenyl-, dichlorodiphenyl-, dichlorodi-o-tolyl-, and dichlorodi-p-tolylsilanes in the presence of 2,3-dimethylbutadiene afforded 1-methyl-1-phenyl-, 1,1-diphenyl-, 1,1-di-o-tolyl-, and 1,1-di-p-tolyl-3,4-dimethyl-1-silacyclopent-3-ene, respectively, while the similar reaction of chloromethyldiphenylsilane with 2,3-dimethylbutadiene afforded 1-(methyldiphenylsilyl)- and 1,4-bis(methyldiphenylsilyl)-2,3-dimethyl-2-butene. A reaction mechanism leading to these products has been discussed.
在 2,3-二甲基丁二烯存在下,电解还原二氯甲基苯基、二氯二苯基、二氯二邻甲苯基和二氯二对甲苯基硅烷分别得到 1-甲基-1-苯基、1,1-二苯基、1,1-二邻甲苯基和 1、而氯甲基二苯基硅烷与 2,3-二甲基丁二烯的类似反应则可得到 1-(甲基二苯基硅基)- 和 1,4-双(甲基二苯基硅基)-2,3-二甲基-2-丁烯。讨论了产生这些产物的反应机理。
