Formation and Properties of a Bicyclic Silylated Digermene

In the presence of PMe(3) or N-heterocyclic carbenes, the reaction of oligosilanylene dianions with GeCl(2)⋅dioxane gives germylene–base adducts. After base abstraction, the free germylenes can dimerize by formation of a digermene. An electrochemical and theoretical study of a bicyclic tetrasilylate...

description In the presence of PMe(3) or N-heterocyclic carbenes, the reaction of oligosilanylene dianions with GeCl(2)⋅dioxane gives germylene–base adducts. After base abstraction, the free germylenes can dimerize by formation of a digermene. An electrochemical and theoretical study of a bicyclic tetrasilylated digermene revealed formation of a comparably stable radical anion and a more reactive radical cation, which were characterized further by UV/Vis and ESR spectroscopy.
