Ketenylidentriphenylphosphoran-Komplexe / Ketenylidenetriphenylphosphorane Complexes

Abstract

Abstract Ketenylidenetriphenylphosphorane complexes of the type L n MC(CO)PPh 3 L n M = CpMn(CO) 2 (2a), CpRe(CO) 2 (2b) and Fe(CO) 4 (3) are obtained by CO substitution reactions. The synthesis of 3 at 80 °C is accompanied by the formation of a Fe 2 (CO) 6 compound with a bridging α-metallated formyl(triphenylphosphane)carbido ligand. From ethylation of 3 arises an Fe 2 (CO) 6 ferrol-type complex 5.
