Coordination chemistry of perfluoroalkylated phosphorus(III) ligands

Palladium(II), platinum(II), rhodium(I), rhodium(III) and iridium(III) complexes of the tridecafluorohexyl-derivatised diphenylethylphosphinite (PPh2OC2H4Rf), phenyldiethylphosphonite {PPh(OC2H4Rf)2}, triethylphosphite {P(OC2H4Rf)3}, triphenylphosphinite (PPh2OC6H4-4-Rf), triphenylphosphonite {PPh(OC6H4-4-Rf)2}, ethyldiphenylphosphine (PPh2C2H4Rf), diethylphenylphosphine {PPh(C2H4Rf)2} and triethylphosphine {P(C2H4Rf)3} ligands are synthesized by conventional ligand displacement and/or halide-bridge cleaved reactions, and their spectroscopic parameters are compared with those for the related ligands lacking the tridecafluorohexyl ponytails.

Graphical abstractThe spectroscopic parameters of palladium(II), platinum(II), rhodium(I), rhodium(III) and iridium(III) complexes of the tridecafluorohexyl-derivatised ligands (L1–L8), synthesized by conventional ligand displacement and/or halide-bridge cleaved reactions, are compared with those for related ligands lacking the tridecafluorohexyl ponytails.Figure optionsDownload full-size imageDownload as PowerPoint slide
