10-aneP3 derivative 1-allyl-3-methyl-1,4,7-triphosphacyclodecane. This macrocycle is the result of two intramolecular hydrophosphination reactions, one that generates a five-membered (chelate) ring with an exo-methyl group and one a six-membered chelate. The [(η5-CpR)Fe]+ fragment also controls the cyclization of 1,2-bis(diallylphosphino)ethane with phenylphosphine to give a ternary complex containing the
