Abstract
The present application provides a hydrodefluorodimerization process, which is useful in the synthesis of, for example, fluoroölefins that can be used as refrigerants, blowers and the like. The process is an “early-stage fluorination” process, wherein precursors containing fluorine are assembled into the desired product using a zerovalent nickel catalyst. Also provided is a liquid composition comprising one or more fluoroölefin produced by this catalytic process.

A process for preparing a hydrofluoroölefin of Formula II
- comprising:
- treating a compound of Formula I with a hydride source, a ligand and nickel[0] catalyst
- where R1, R2 and R3 are each independently H, F, RF, n-alkyl, isoalkyl, tert-alkyl, cycloalkyl, aryl, alkenyl, NR2, OR, SR, or R3Si, where R is an n-alkyl, isoalkyl, tert-alkyl, cycloalkyl, aryl, or alkenyl.
