Amine-containing acyclic hydrofluoroethers and methods of using the same

A acyclic fluorinated compound of formula (I)

• where:
• each Rh is independently H or CH3;
• X is selected from F or CF3, and Y is selected from H, F, or CF3, wherein when X is CF3then Y is F and when Y is CF3then X is F;
• each Rf1 is independently selected from a linear or branched perfluorinated alkyl group comprising 1-8 carbon atoms and optionally comprising at least one catenated atom selected from O, N, or combinations thereof;
• or the two Rf1 groups are bonded together to form a fluorinated ring structure comprising 4-8 carbon atoms and optionally comprising at least one catenated atom selected from O, N, or combinations thereof;
• A is selected from F, or CF3;
• Z is selected from H, F or CF3;
• and
• Q is selected from (i) a F atom, (ii) a Cl atom, (iii) a linear, cyclic, or branched perfluorinated alkyl group comprising 1-8 carbon atoms and optionally comprising at least one catenated atom selected from O, N, or combinations thereof, or (iv) a G(Rf2)e group, where G is an O atom or a N atom wherein:
• when Q is a Cl atom, then Z and A are F atoms;
• when G is O then e is 1, Z is H, F or CF3;
• A is F;
• and Rf2 is a linear or branched perfluorinated alkyl group comprising 1-10 carbon atoms and optionally comprising at least one catenated atom selected from O, N, or combinations thereof;
• when G is N then e is 2, and each Rf2 group is independently a linear or branched perfluorinated alkyl group comprising 1-8 carbon atoms and optionally comprising at least one catenated atom selected from O, N, or combinations thereof or the two Rf2 groups are bonded together to form a fluorinated ring structure comprising 4-8 carbon atoms and optionally comprising at least one catenated atom selected from O, N, or combinations thereof, with the proviso that when A is CF3 then Z is F, and when Z is CF3 then A is F.
