Patent ID: 7531701

Claim:
A process for the preparation of an allyloxytrifluoropropene derivative represented by the formula: CF 3 CH═CR 1 (OCH 2 CR═CH 2 ) wherein: R 1 is selected from the group consisting of: hydrogen, fluoro, and allyloxy group represented by the formula: —OCH 2 CR═CH 2 wherein R is selected from the group consisting of: hydrogen and methyl; and said process comprising the steps of: contacting (i) a compound represented by the formula: CF 3 CH═CR 2 R 3 wherein R 2 is selected from the group consisting of: hydrogen, chloro, and fluoro and wherein R 3 is chloro or fluoro; and (ii) an allyl alcohol derivative represented by the formula: HOCH 2 CR═CH 2 wherein R is selected from the group consisting of: hydrogen and methyl; wherein said contacting is carried out in the presence of a base and optionally a solvent at a temperature and length of time sufficient to produce said allyloxytrifluoropropene derivative.
