Dinitrogen Reduction by a Chromium(0) Complex Supported by a 16-membered Phosphorus Macrocycle
An unexpected reaction leading to the synthesis and characterization of two Cr-N2 complexes supported by cyclic phosphorus macrocycles that contain pendant amine bases. Reactivity with acid produced hydrazine and ammonia, illustrating the first example of N2 reduction by a "Chatt-type" chromium dinitrogen complex. Computational analysis examined the initial N2 protonation steps, highlighting the thermodynamically preferred Cr products involved in N2 reduction.
