and phenylsilane was discussed to access aryl- or alkyl-substituted urea derivatives. This procedure was characterized by adopting hydrosilane to promote the formation of ureas directly, without the need to prepare silylamines in advance. Control reactions suggested that FeCl3 was a favorable additive for the generation of ureas, and this 1,5,7-triazabicyclo[4.4.0]dec-5-ene-catalyzed reaction might
讨论了使用CO 2,胺和苯基硅烷的方法,以获取芳基或烷基取代的脲衍生物。该方法的特征在于采用氢硅烷直接促进脲的形成,而无需事先制备甲硅烷基胺。对照反应表明,FeCl 3是产生脲的有利添加剂,该1,5,7-三氮杂双环[4.4.0] dec-5-ene催化的反应可能通过亲核加成,硅迁移以及随后的过程进行。甲硅烷基氨基甲酸酯的正式取代。
