Abstract

The Mayr carbyne synthesis is readily extendable to aminomethylidyne complexes of group 6 metals, e.g., [M(≡CNiPr2)(O2CCF3)(CO)3(PPh3)] (M = Cr, Mo, W) result from successive treatment of [M(CO)6] with LiNiPr2, (CF3CO)2O and PPh3. The same approach with [Fe(CO)5] however, provides the trifluoromethyl-carbamoyl complex [Fe(η-OCNiPr2)(CF3)(CO)2(PPh3)], whilst replacing LiNiPr2 with LiC6H3Me2−2,6 provides the dinuclear complex [Fe2(μ-OCC6H3Me2-2,6)2(CO)5(PPh3)].Reaction of [M(≡CNiPr2)(O2CCF3)(CO)3(PPh3)] with K[HB(pz)3] (pz = pyrazol-1-yl) provides [M(≡CNiPr2)(CO)2{HB(pz)3}] whilst similar treatment of [Fe(η-OCNiPr2)(CF3)(CO)2(PPh3)] provides the unusual metallaoxetene complex [Fe{C(NiPr2)OCF2}(CO){HB(pz)3}] via fluoride abstraction.
