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 CH bonds of two MeCH groups donate two additional electrons to achieve the stable 34 VE configuration.
