各种有机硅化合物，如芳基、乙烯基和炔基二硅烷、硅环丁烷和硅环丁烯，以及α-硅基酮和-重氮甲烷的激光闪光光解导致反应性硅烯的形成，可以直接在溶液中检测到，这使得详细研究它们与亲核试剂反应的动力学和机理成为可能。现在已经用这些方法研究了30多个瞬时沉默分子，提供了系统地评估硅和碳取代基对Si=C键反应活性的影响的机会。
Laser flash photolysis of various organosilicon compounds such as aryl-, vinyl-, and alkynyldisilanes, silacyclobutanes and silacyclobutenes, and alpha-silylketenes and -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.
