The Selenium-Based Hexameric Macrocycle [(Se)P(μ-NtBu)2P(μ-Se)]6

Head‐to‐Tail: The Wurtz reaction of the dimer [(Cl)(Se)P(μ‐NtBu)]2 (1) with sodium metal gives the inorganic macrocycle [(Se)P(μ‐NtBu)2P(μ‐Se)]6 (2), arising from cyclization of a selenium‐centered nucleophilic intermediate. The inorganic macrocyclic backbone contains alternating PIII and PV cente...

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