Abstract
Fluoromethyl 1,1,1,3,3,3-hexafluoro-2-propyl ether is prepared by reacting bromine trifluoride and methyl 1,1,1,3,3,3-hexachloro-2-propyl ether or chloromethyl 1,1,1,3,3,3-hexachloro-2-propyl ether. The mixed fluorochloro ether intermediates having the formula of ##STR1## (wherein x+y=3, a+b=3, and Z=H Cl, or F) are converted to fluoromethyl 1,1,1,3,3,3-hexafluoro-2-propyl ether by reactions with bromine trifluoride.
