Process for the preparation of dianions and of alpha-substituted carboxylic acids and their decarboxylated derivatives |
| abstract |
A PROCESS FOR THE PREPARATION OF DIANIONS OF STRAIGHT CHAIN SATURATED AND UNSATURATED ALIPHATIC CARBOXYLIC ACIDS AND OF A-SUBSTITUTED CARBOXYLIC ACIDS AND THEIR DECARBOXYLATED DERIVATIVES. THE CARBOXYLIC ACID IS METALATED WITH LITHIUM DISOPROPYLAMIDE IN THE MIXED SOLVENT SYSTEM TETRAHYDROFURAN-HEXANE-HERAMETHYLPHOSPHORAMIDE AND THE METALATED FATTY ACID IS REACTED IN THE SAME SOLVENT SYSTEM WITH AN ELECTROPHILE TO PRODUCE THE DESIRED A-SUBSTITUTED CARBOXYLIC ACID. DECARBOXYLATION IS ALSO EFFECTED IN THE SAME SOLUTION THUS MAKING THIS ESSENTIALLY A ONE STEP PROCESS FOR ANY OF THE PRODUCTS. |
