The transformation of phosphorous oxyacids into the corresponding fluorophosphines was mediated by [RuCp(PPh3)(2)Cl] under mild reaction conditions using a soft deoxofluorinating agent. The reaction is selective, proceeds with high yields and can be extended to a wide range of phosphorous oxyacids once coordinated to the ruthenium synthon [RuCp(PPh3)(2)](+) as their hydroxyphosphine tautomer. Deoxofluorination of phenylphosphinic acid was also mediated by [RuCpR(CH3CN)(3)]PF6, where Cp-R: Cp = C5H5, Cp* = C5Me5, and [Ru(eta(6)-p-cymene)(mu-Cl)Cl](2). X-Ray single crystal structures of the two new derivatives, [RuCp(PPh3)(2){PhP(OH)(2)}]CF3SO3 and [Ru(eta(6)-p-cymene)Cl-2{PhP(OH)(2)}] have been determined.
