Photoinduced reductive perfluoroalkylation of phosphine oxides: synthesis of P-perfluoroalkylated phosphines using TMDPO and perfluoroalkyl iodides
A photoinduced reaction between TMDPO (diphenyl(2,4,6-trimethylbenzoyl)-phosphine oxide) and perfluoroalkyl iodides successfully affords P-(perfluoroalkyl)diphenylphosphines as promising ligands for recyclable catalysts. Interestingly, the perfluoroalkylation reaction involves the reduction of phosphorus(v) compounds to phosphorus(iii) species. The advantages of the present reaction include the use of an air-stable phosphorus source and good yields of P-perfluoroalkylphosphines in short reaction times.

Synthesis and properties of perfluoroalkyl phosphine ligands: Photoinduced reaction of diphosphines with perfluoroalkyl iodides
A 'F'lurry of activity: The title reaction provides a convenient procedure for direct synthesis of perfluoroalkylated phosphines. The synthesized phosphine n-C10F21PPh2 forms a complex with palladium(II) to give 1 and several runs of coupling reactions are attained with n-C10F21PPh2 by using a fluorous/organic biphasic system.
