The phosphines R(RF)2P (RF= CF3, R = Me, Bun, Bui, Ph; RF= C3F7, R = Bun, Ph) and Bu2n(CF3)P, and the phosphinous chloride Bu(CF3)PCl, have been made from the chlorides (RF)2PCl or RFPCl2 and organolithium compounds in ether–hexane at –78°. The phosphines R2(C3F7)P (R = Et, Ph, CF3) and CF3(C3F7)2P have been made from the compounds R2PCl or CF3PCl2 and heptafluoropropyl-lithium. The phosphine (CF3)2(C3F7)P
