Acyclic catena-diphosphinodiphosphonium dications [R3P-PR'-PR'-PR3]2+ or bisphosphine-diphosphenium complexes [R3PPR'-PR'PR3]2+: synthesis by reductive P-P coupling of [R3P-PR'Cl]+ and phosphine ligand exchange.

Abstract

The acyclic tetraphosphorus dication [Ph3P-PPh-PPh-PPh3]2+ has been formed by the reductive coupling of [Ph3P-PPhCl]+, providing a new synthetic method for the systematic development of catena-phosphorus cations. Ligand exchange (Ph3P for Me3P) gives [Me3P-PPh-PPh-PMe3]2+, implicating these dications as bisphosphine-diphosphenium complexes.
