Fusion of a 1,3-diboraruthenocene to form a slipped mu-hexahydrotetraboranaphthalene triple-decker complex with two axial C--H bonds.
Colliding double deckers: Addition of zinc to a reaction mixture of [{Cp*RuCl}(4)]/pentamethyl-2,3-dihydro-1,3-diborole (C(3)B(2)Me(5)H) in THF leads to three known double- and triple-decker complexes of [C(3)B(2)Me(5)](-), and unexpectedly to the slipped triple-decker (see picture) with two fused diborole rings. The endo C--H bonds of two MeC--H groups donate two additional electrons to achieve the stable 34 VE configuration.
