Silylenes and Germylenes: The higher homologues of carbene...

As a lot of work has been carried out on carbenes by various scientists, but their higher homologues known as silylenes and germylenes have attracted the researchers within past two decades. The first satble silylene was isolated by West et al. in 1994, while the first stable germylene was considered as acacGeI complex by Stobart et al. in 1979.
