successive reaction of heterosubstituted diallyl amines 2, obtained from diallyl amine 1, with n-butyllithium and tert-butyllithium leads to dianionic species 3, which have been characterized by reaction with different electrophiles (deuterium oxide, dimethyl disulphide, chlorotrimethylsilane, and tributylin chloride) yielding compounds 4; the treatment of the intermediate 3a with tert-butyllithium affords
从二烯丙基胺1得到的杂取代的二烯丙基胺2与正丁基锂和叔丁基锂的连续反应导致生成双阴离子3,其特征是与不同的亲电试剂(氧化氘,二甲基二硫化物,氯三甲基硅烷和三丁基氯化锡)反应)得到化合物4; 中间体3a用叔丁基锂处理得到三阴离子5,它与二氧化碳,二氯二甲基硅烷和二氯二乙基锗反应生成氨基酯6,氮杂硅藻土和氮杂锗烷衍生物7和8。
