( eta 3-PHOSPHAALLYL)IRON COMPLEXES: SYNTHESIS AND PRELIMINARY CHEMICAL STUDY.

Vinylchlorophosphine P-W(CO)//5 complexes react in boiling toluene with left bracket CpFe(CO)//2 right bracket //2 to give mu //2-vinylphosphido complexes whose phosphorus atom bridges a W(CO)//5 and a Fe(CO)//2Cp unit. Upon short irradiation, these mu //2-complexes yield ( eta **3-1-phosphaallyl)Fe(CO)Cp complexes as mixtures of two isomers. These two series of isomers undergo a slow equilibration in solution. This equilibration takes place via the decoordination and the upside-down rotation of the vinyl unit followed by a recomplexation of this unit by the iron atom. These two series of isomers differ mainly in the magnitude of the **2J(P-C-H) coupling constants within the phosphaallyl unit. The constant is high (ca. 30 Hz) when the W-P-C-H dihedral angle is close to 0 degree and low (ca. 0 Hz) when this angle is close to 180 degree .
