The activation of two groups on the silane occurs in a stepwise fashion:  initial oxidative addition of a Si−X bond, followed by 1,2-migration (α-elimination) of the Si−Cl group to the metal. Reversible dissociation from the Ru(II) center leads to free silylene, which can be preferentially trapped with Ru(0) complexes to generate a zero-valent silylene complex, [N3]Ru(N2){Si(NN)}, which also contains a terminal dinitrogen ligand. %I ACS Publications
