Head‐to‐Tail : The Wurtz reaction of the dimer [(Cl)(Se)P(μ‐N t Bu)] 2 ( 1 ) with sodium metal gives the inorganic macrocycle [(Se)P(μ‐N t Bu) 2 P(μ‐Se)] 6 ( 2 ), arising from cyclization of a selenium‐centered nucleophilic intermediate. The inorganic macrocyclic backbone contains alternating P III and P V centers and possesses an 8.2‐Å‐diameter cavity.
