The radical-induced cyclization of 1,2-bis(phosphanyl)ethane and diallylphenylphosphane coordinated to a (pentamethylcyclopentadienyl)iron(II) template gives the first ten-membered triphosphorus macrocycle with three inequivalent phosphorus centers [Eq. (1); AIBN = azobisisobutyronitrile].

The complex [(η5-Me3SiC5H 4)Fe(10aneP3-H2H3)]+, where Me3SiC5H4 is trimethylsilylcyclopentadienyl and 10-aneP3-H2,C 2H3 is 1-vinyl-1,4,8-triphosphacyclodecane, has been prepared by the base-catalyzed template cyclization of 1,3-bis(phosphino)propane (1,3-bpp) and trivinylphosphine (tvp) at the metal center. A related radical-initiated iron-template reaction between 1,2-bis(phosphino)ethane (1,2-bpe) and triallylphosphine (tap) gave [(η5-C 5Me5)Fe(Me-10aneP3-H2,C 3H5)]+, where C5Me5 is 1,2,3,4,5-pentamethylcyclopentadienyl and Me-10aneP3-H 2.C5H5 is the unsymmetric 10-anePs derivative 1-allyl3-methyl-l,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 symmetrical 11-membered macrocycle 1-phenyl-4,8-diallyl-l,4,8-triphosphacycloundecane, in addition to the unsymmetrical 10-aneP3 derivative.
