Group-Transfer Reactions of Nickel-Carbene and -Nitrene Complexes with Organoazides and Nitrous Oxide that Form New C=N, C=O, and N=N Bonds

摘要

Nitrous oxide (N_2O) and organoazides (N_3R') are energy-rich molecules that undergo a variety of reactions with group 10 transition metal complexes resulting in transfer of an "O" or "NR" moiety to the metal with loss of dinitrogen. Complexes of the type L_2NiR_2 (L = PMe_3; L_2 = bipyridine, phenanthroline; R = alkyl, aryl) undergo quite general insertion reactions with nitrous oxide to afford alkoxide or aryloxide products L_2NiR(OR) and with organoazides to yield amide derivatives L_2NiR(NR'R) upon N_2 extrusion.
