    Abstract: A METHOD OF CARBOXYLATING INDENE, CYCLOPENTADIENE, FLUORENE AND HYDROCARBYL CYANIDE BY CONTACTING SAID COMPOUNDS WITH CARBON DIOXIDE UNDER SUBSTANTIALLY ANHYDROUS CONDITIONS IN THE PRESENCE OF A GUANIDINE OF THE FORMULA:

    R1-N(-R2)-C(=N-R3)-N(-R3)-R4

    WHERE R1 THROUGH R5 ARE HYDROGEN OR ALKYL OF FROM 1 TO 5 CARBONS AND ACIDIFYING THE RESULTANT REACTION MIXTURE TO FORM THE CARBOXYLIC ACID DERIVATIVE AND RECOVERING SAID DERIVATIVE THEREFROM.
