Three phosphines bearing halodifluoromethyl group were obtained starting from chlorodiphenylphosphine. Silicon reagents Me3SiCF2X (X=Cl, Br) were used to install chloroor bromodifluoromethyl group to the phosphorus atom. Iododifluoromethyl-substituted phosphine was prepared by bromine/iodine exchange.
