Abstract

Sequential room-temperature carbonyl substitution of [N(PPh3)2][Fe3H(CO)11] with isonitriles CNR (R = Me, Et, or Pri) yields the substituted anions [N(PPh3)2][Fe3H(CO)11-x(CNR)x](x= 1 or 2), which on alkylation using R'3OBF4(R'= Me or Et) or acidification using CF3SO3H yield the complexes [Fe3H(CO)10(CNRR')](R = R'= Et; R = Pri, R'= Me or Et; R = Me, R'= Et; R = Me, R'= H) and [Fe3H(CO)9,(CNRR')(CNR)](R = R'= Et). At higher temperatures, an insertion of isonitrile into the M-H-M bond is observed to yield, after acidification, the complex [Fe3H(CO)9(CH=NPri)]. The fluxional properties of these molecules are discussed.
