C07C 17/266
C07C 17/26
US Classification:
570172, 570171
Abstract:
A process is disclosed for making RRRCCRRF wherein R is selected from the group consisting of CH, CHF, CHF, and F(CF)CHCHwhere n is an integer from 1 to 10, each Ris independently selected from the group consisting of H, Cl, F and CF, and each Ris independently selected from the group consisting of H, F and CF. The process involves reacting RF with RRC═CRRin the presence of SbFto produce a product mixture comprising RRRCCRRF, wherein the reaction temperature is from about −60 C. to about −10 C. , provided that total number of carbon atoms in RRC═CRRis 5 or less.
