Abstract

Disclosed is a method for producing fluorinated organic compounds, including reacting CF 2 ═CFCl with CH 2 FCl under conditions effective to produce a product composition including CF 3 CClFCH 2 Cl. The present invention also relates to the production of hydrofluoropropenes, which preferably comprises converting at least one compound of formula (I): CF 3 CF n CH m X a−m   (I) to at least one compound of formula (II) CF 3 CZCHZ  (II). where each X is independently Cl, F, I or Br; each Z is independently H or F; n is 1 or 2; m is 1, 2 or 3, provided that when n is 1, m is 1 or 2; a is 2 or 3, and a−m≧0. Certain embodiments include the step of reacting fluorinated C2 olefin, such as tetrafluoroethylene, with a C1 addition agent under conditions effective to produce a compound of formula (I).

Claims (10)

1. A method of preparing fluorinated organic compounds comprising:

reacting CF 2 ═CFCl with CH 2 FCl under conditions effective to produce a product composition comprising CF 3 CClFCH 2 Cl.

2. The method of claim 1 wherein the reacting step is conducted in a gas phase.

3. The method of claim 1 wherein the reacting step is in the presence of a Ni-mesh catalyst.

4. The method of claim 1 wherein the product composition further comprises F 2 ClCCF 2 CH 2 Cl.

5. A method of preparing fluorinated organic compounds comprising:

reacting CF 2 ═CFCl with CH 2 FCl under conditions effective to produce CF 2 ClCF 2 CH 2 Cl.

6. The method of claim 5 wherein the reacting step is conducted in a gas phase.
