Electroneg. phosphine oxides were reduced to corresponding phosphines by trichlorosilane-mediated oxygen transfer to sacrificial PPh3 or P(OEt)3 with excellent yields. The diphosphine dioxides 2,2′-(Ar2PO)-1,1′-binaphthalene (1a-e, Ar = 3,5-(CF3)2C6H3, 4-CF3C6H4), Ar2POCH2CH2POAr2 (1g, Ar = C6F5), monophosphine oxides Ar3PO and Ar2PAr1 (1h and 1f, resp.; Ar = 3,5-(CF3)2C6H3, Ar1 = 1,1′-binaphthalene-2-yl) were deoxygenated to the corresponding phosphines (2a-h) by reaction with HSiCl3 in the presence of PPh3 or tri-Et phosphite, acting as sacrificial oxygen acceptors, which shift the deoxygenation reaction equilibrium to the corresponding phosphines. The advantage of the new method includes milder conditions and considerably shortened reaction times. Mechanistic studies about the oxygen transfer between the starting phosphine oxide and the sacrificial triphenylphosphine are also presented.
