Reactions of the dicarbonyl substituted cyclopentadienyl nitrosyl manganese complex cation [(π-C5H4)Mn(NO)(CO)2]+with some nitrogen and phosphorus donor ligands
The syntheses of monocationic complexes, [(π-C-H4R)Mn(NO)L2]+, [(π-C5H4R)Mn(NO)LL′]+, and [(π-C5H4R)-Mn(NO)(N–N)]+[R = H or Me, L =γ-picoline, PMe2Ph, PPh3, or P(OPh)3, L = CO and L′= P(OPh)3 or PPh3, or L =γ-picoline and L′= P(OPh)3 or PPh3, and where N–N =α,α′-bipyridyl, o-phenanthroline, or N-(2-pyridylmethylene)-p-toluidine] by reaction of [(π-C5H4R)Mn(NO)(CO)2][PF6] with these ligands is described. The reactions with α-picoline, and the use of triethylamine as a catalyst in the formation of the phosphine complexes, are reported. Treatment of [(π-C5H4R)Mn(NO)(CO)2]+ with triethylamine in acetone in the absence of other ligands gives [(π-C5H4R)Mn(NO)(CO)]2.
