Abstract
Reactions between [(π-C5H5)Fe(CO)2X](X = Cl, Br) and CuC2R (R = Ph, p-MeC6H4, p-FC6H4, or C6F5) afford the complexes [{(π-C5H5)Fe(CO)2(C2R)CuX}2]. In these, the iron acetylide group is π-bonded to copper; the complexes are dimeric via copper–halogen bridges. An alternative method of synthesis is from the acetylide and the copper(I) halide in acetone. Reactions between these complexes and [Fe2(CO)9] afford trinuclear [(π-C5H5)Fe3(C2R)(CO)7].Keywords
