Changing the Reactivity of Zero- and Mono-Valent Germanium with a Redox Non-Innocent Bis(silylenyl)carborane Ligand
Original language description
Using the chelating C,C '-bis(silylenyl)-ortho-dicarborane ligand, 1,2-(RSi)(2)-1,2-C2B10H10 [R=PhC(NtBu)(2)], leads to the monoatomic zero-valent Ge complex (""germylone"") 3. The redox non-innocent character of the carborane scaffold has a drastic influence on the reactivity of 3 towards reductants and oxidants. Reduction of 3 with one molar equivalent of potassium naphthalenide (KC10H8) causes facile oxidation of Ge-0 to Ge-I along with a two-electron reduction of the C2B10 cluster core and subsequent Ge-I-Ge-I coupling to form the dianionic bis(silylene)-supported Ge-2 complex 4. In contrast, oxidation of 3 with one molar equivalent of [Cp2Fe][B{C6H3(CF3)(2)}(4)] as a one-electron oxidant furnishes the dicationic bis(silylene)-supported Ge-2 complex 5. The Ge-0 atom in 3 acts as donor towards GeCl2 to form the trinuclear mixed-valent Ge-0 -> Ge-II <- Ge-0 complex 6, from which dechlorination with KC10H8 affords the neutral Ge-2 complex 7 as a diradical species.
