The reaction of trans-[M(N<sub>2</sub> )<sub>2</sub> (dppe)<sub>2</sub> ] (M=Mo, 1<sub>Mo</sub> , M=W, 1<sub>W</sub> ) with B(C<sub>6</sub> F<sub>5</sub> )<sub>3</sub> (2) provides the adducts [(dppe)<sub>2</sub> M=N=N-B(C<sub>6</sub> F<sub>5</sub> )<sub>3</sub> ] (3) which can be regarded as M/B transition-metal frustrated Lewis pair (TMFLP) templates activating dinitrogen. Easy borylation and silylation of the activated dinitrogen ligands in complexes 3 with a hydroborane and hydrosilane occur by splitting of the B-H and Si-H bonds between the N<sub>2</sub> moiety and the perfluoroaryl borane. This reactivity of 3 is reminiscent of conventional frustrated Lewis pair chemistry and constitutes an unprecedented approach for the functionalization of dinitrogen.
