elimination of 2-[N,N-bis(trimethylsilyl)amino]alkenyl (diethyl)phosphates affords 1-[N,N-bis(trimethylsilyl)amino]-1,2-alkadienes (“allenamines”). Conjugatively-substituted allenamines undergo further metalation under these eliminative conditions to form allenyl carbanions which may be trapped in situ by chlorotrimethylsilane to give 3-trimethylsilyl-or 3,3-bis(trimethylsilyl)-N,N-bis(trimethylsilyl)allenamines
二异丙基氨基锂诱导的2- [ N,N-双(三甲基甲硅烷基)氨基]链烯基(二乙基)磷酸酯的消除得到1- [ N,N-双(三甲基甲硅烷基)氨基] -1,2-链二烯(“亚胺基”) 。在这些消除条件下,共轭取代的烯丙胺进一步金属化,形成烯丙基碳负离子,这些碳烯基碳负离子可以被氯三甲基硅烷原位捕获,得到3-三甲基甲硅烷基-或3,3-双(三甲基甲硅烷基)-N,N-双(三甲基甲硅烷基)亚烷基胺。
