Routes to unique palladium A-frame complexes with a bridging fluoro-ligand

Treatment of a toluene solution of [PdMe2(Cy2PCH 2PCy2)] (1) with pentafluoropyridine in the presence of traces of water affords the generation of the A-frame complexes [(PdMe) 2{μ-κ2(P,P)Cy2PCH2PCy 2}2(μ-F)][SiMeF4] (2a) and [(PdMe) 2{μ-κ2(P,P)Cy2PCH2PCy 2}2(μ-F)][OC5NF4] (2b). If the reaction is performed in an NMR tube equipped with a PFA inliner, complex 2b is produced, only. Treatment of 1 with pentafluoropyridine in the presence of an excess water yields the pyridyloxy complex [PdMe(OC5NF 4)(Cy2PCH2PCy2)] (3). Compound [(PdMe)2{μ-κ2(P,P)Cy2PCH 2PCy2}2(μ-F)][FHF] (2c) bearing a bifluoride anion instead of SiMeF4- or OC5NF 4- can be generated by reaction of 1 with substoichiometric amounts of Et3N·3HF. The analogous complex [(PdMe)2{μ-κ2(P,P)Ph2PCH 2PPh2}2(μ-F)][FHF] (5c) has been synthesized by addition of Ph2PCH2PPh2 to a solution of [PdMe2(Me2NCH2CH2NMe2)] (4) in THF and subsequent treatment of the reaction mixture with Et 3N·3HF. The structure of the A-frame complex 5c has been determined by X-ray crystallography. The Royal Society of Chemistry 2005.
