The new 1,3‐bis(dimethylamino) derivative 1 is isoelectronic with decamethyl[5]radialene. The analogous 1,3‐dimethyl compound 2 undergoes slow 1,5‐sigmatropic H shift to give a 1,3‐diborafulvene. This process is faster in the reaction with [Mo(CO) 6 ], whereby the product is the [Mo(CO) 4 ] complex 3.
