title: Synthesis of 1,4,7-triphenyl-1,4,7-triphosphacyclononane: the first metal-free synthesis of a [9]-aneP(3)R(3) ring.
abstract: The 1,4,7-triphenyl-1,4,7-triphosphacyclononane ([9]-aneP(3)Ph(3)) macrocycle was synthesized through the reaction of lithium bis(2-phenylphosphidoethyl)phenylphosphine with 1,2-dichloroethane. [9]-aneP(3)Ph(3) was subsequently coordinated to a Mo(0) metal center and isolated as the fac-Mo([9]-aneP(3)Ph(3))(CO)(3) metal complex.
