Abstract: Method of carboxylating an organic compound of the group of RC*CH, RCH2CN, indene or cyclopentadiene where R is hydrocarbyl comprising contacting under anhydrous conditions in an inert atmosphere and in the presence of an inert, aprotic, dipolar, liquid solvent, said compound with a carbonated metal phenoxide, the metal phenoxide of the formula:
WHERE X is sodium or potassium, R1 is hydrogen or alkyl, and subsequently acidifying the resultant intermediate product to form the carboxylated product.
