The base‐catalyzed cyclization of 1,2‐bis(phosphanyl)ethane with trivinylphosphane on a pentamethylcyclopentadienyl iron template results in the high‐yield synthesis of the first triphosphacyclononane derivative containing one vinyl‐functionalized and two secondary phosphanes. The vinyl triphosphacyclononane is readily hydrogenated and alkylated to give the tritertiary 1,4,7‐triethyltriphosphane macrocycle 1 .
