Dyker CA, Burford N, Lumsden MD, Decken A: 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. J Am Chem Soc. 2006 Aug 2;128(30):9632-3.
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. |
