| titleOfInvention | Process for producing fluorinated acids |
| abstract | FLUOROALIPHATIC VINYLIC CARBOXYL-CONTAINING COMPOUNDS ARE PREPARED BY THE FOLLOWING STEPS: FIST, REACTING IN GAS PHASE HYDROGEN BROMIDE WITH A VOLATILE FLUOROLIPHATIC COMPOUND CONTAINING AT LEAST ONE VINYLIC CHLORINE ATOM IN WHICH NONDOUBLY BONDED CARBON ATOMS ARE SUBSTITUTED ONLY BY FLORINE AND FLUROALKYL GROUPS CONTAINING FROM ONE TO SIX CARBON ATOMS, IN THE PRESENCE OF A METAL SALTACTIVE CARBON CATALYST, THEREBY EFFECTING THE REPLACEMENT OF AT LEAST ONE VINYLIC CHLORINE ATOM BY BROMINE; SECOND, REACTING A BROMINATED PRODUCT ON STEP (1) WITH ALKALI METAL IODIDE, THE REACTANTS BEING DISSOLVED IN DIMETHYLFORMAMIDE, THEREBY EFFECTING A SUBSTITUTION OF AT LEAST ONE VINYLIC BROMINE ATOM BY IODINE; THIRD, REACTING AN IODIDE RESULTING FROM STEP (2) WITH A LITHIUM ALKYL TO PRODUCE AN ORGANOLITHIUM INTERMEDIATE COMPOUND AND SUBSE-N QUENTLY TREATING SAID INTERMEDIATE COMPOUND WITH CARBON DIOXIDE TO PRODUCE A LIHIUM SALT WHICH HYDROLYZERS TO A CARBOXYLIC ACID. THE CARBOXYLIC ACIDS OF THE INVENTION ARE MUCH STRONGER ACIDS THAN THE CORRESPONDING SATURATED STRUCTURES AND MAY BE CONVERTED INTO USEFUL SIMPLE DERIVATIVES. |
