Nitrosobenzene as a two-electron ligand in ?-cyclopentadienyl and carbonyl complexes with group VI and VII transition metals

Interactions of Organic Nitroso Compounds with Metals

“…The coordinated PhNO groups in M(CO) 5 (PhNO) (M ) Cr, Mo, W) undergo facile reduction in THF to give the M(CO) 5 (PhNH 2 ) compounds. 252 A similar reduction of W(CO) 5 (t-BuNO) to W(CO) 5 (t-BuNH 2 ) is known. 112 Becker and Bergman developed the LiAlH 4 reduction of the dinitrosoalkane ligands in cobalt complexes (e.g., those in eqs 25 and 37) to primary vicinal diamines.…”

“…(3) Reduction of Coordinated RNO . The coordinated PhNO groups in M(CO) 5 (PhNO) (M = Cr, Mo, W) undergo facile reduction in THF to give the M(CO) 5 (PhNH 2 ) compounds . A similar reduction of W(CO) 5 ( t -BuNO) to W(CO) 5 ( t -BuNH 2 ) is known …”
