Cobalt(-) triphos dinitrogen complexes: activation and silyl-functionalisation of N
The cobalt dinitrogen complexes [{(EP 3 Ph )Co(μ-N 2 )} 2 Mg(THF) 4 ], with triphos ligand scaffolds (EP 3 Ph , E = N or CMe), were prepared via two electron reductions of the Co( i ) precursors [CoCl(EP 3 Ph )]. Both complexes showed high degrees of N 2 activation owing to the formation of a rare M...

via
two electron reductions of the Co(

activation owing to the formation of a rare M-NN-Mg-NN-M bridging-magnesium core. These systems showed further N

functionalisation reactivity by silylation, forming silyldiazenido complexes [(EP
