Pyridine, thiophosphine, and selenophosphine complexes of the phenylphosphine dication

Compounds of the generic formula [PhPL][OTf]2 with L = bipyridine (bipy) and 4,4'-di(tert-butyl)-2,2'-bipyridine (Bbipy), and [PhPL2][OTf]2 with L = dimethyl-amminopyridine (dmap), tricyclohexyl-thiophosphine and tricyclohexyl-selenophosphine have been prepared by the reaction of dichlorophenylphosphine with two equivalents of trimethylsilyl triflate and the respective ligand. The new complexes of the phenylphosphine dication with this variety of ligands expands the scope of coordination complexes involving phosphorus as an acceptor.
