Methods for the dehalogenation of various haloethers are disclosed, comprising providing a haloether having the formula CX'3-[CY2]n-O- CZ2-CX3 in which n=0 or 1, and X', Y, Z and X are specifically disclosed combinations of hydrogen, fluorine, chlorine and bromine such that the molecule includes at least one reducible group, but where both portions of any ethyl groups present are not reducible. Dehalogenation of these haloethers is carried out by contacting same with a hydrogen donor comprising an amine, preferably a primary or secondary amine or a primary, secondary or tertiary alkanol amine. The amine is preferably used in combination with a catalyst, such as a variant metal or a salt thereof, such as copper or a copper salt. |
