A base-stabilized -phosphonio--amino-silyne was synthesized, using an original method, through a coupling reaction between two Lewis-base-stabilized low-valent species: a silyliumylidene ion and a P,S-bis-ylide [C(0)-complex]. This new isolable cationic silyne displays remarkably high stability at room temperature [ = 7 days in tetrahydrofuran (THF)] and a unique silyne reactivity thanks to the effect of phosphonio substituent.
一种基于稳定的膦基-氨基-硅炔通过两种路易斯碱稳定的低价物种之间的偶联反应合成,这两种低价物种是:硅亚基离子和 P,S-双亚基 [C(0)-络合物]。这种新的可分离的阳离子硅炔在室温下显示出非常高的稳定性(在四氢呋喃中稳定 7 天),并且由于膦基取代基的影响,具有独特的硅炔反应性。
