-diazomethanes leads to the formation of reactive silenes which can be detected directly in solution, allowing detailed studies of the kinetics and mechanisms of their reactions with nucleophiles. Over 30 transient silenes have now been studied by these methods, providing the opportunity to systematically assess the effects of substituents at silicon and carbon on the reactivity of the Si=C bond.
各种有机硅化合物(例如芳基、乙烯基和炔基乙硅烷、硅杂环丁烷和硅杂环丁烯以及 α-甲硅烷基烯酮和 -重氮甲烷)的激光闪光光解导致形成可直接在溶液中检测到的反应性硅烯,从而可以对动力学进行详细研究以及它们与亲核试剂的反应机制。现在已经通过这些方法研究了 30 多种瞬态硅烯,提供了系统评估硅和碳上的取代基对 Si=C 键反应性的影响的机会。
