A surprisingly straightforward cyclotetramerization of t BuC ≡ P in the coordination sphere of an η 8 ‐cyclooctatertraene–zirconium complex yields 1,3,5,7‐tetraphosphabarrelen 1 . The bicyclic compound is initially bound to the Zr atom through two PC bonds, but can easily be liberated from the complex by reaction with hexachloroethane.
