Unusual phosphinoacetylene–iron carbonyl complex: synthesis and X-ray structure of [Fe3(CO)7{Ph2PC(CO2Me)C(CF3)C2(CF3)}(PPh2)]2C6H6
Abstract
Dodecacarbonyltri-iron reacts with 3,3,3-trifluoropropynyldiphenylphosphine to give a trinuclear iron(O) complex having the Fe3(CO)12skeleton, a new type of delocalized 4-carbon chain, a bridging dipheylphosphido-ligand, and a methoxycarbonyl group derived from both the methanol used as a stabilizer for [Fe3(CO)12] and a CO molecule.
