Patent ID: 7253300

Claim:
A process for producing tricyclo[5.2.1.0 2,6 ]decane-2-carboxylic acid ester by reacting tricyclo[5.2.1.0 2,6 ]deca-3-ene with carbon monoxide and alcohol in the presence of HF, the process comprising (a) a step of reacting tricyclo[5.2.1.0 2,6 ]deca-3-ene with carbon monoxide until carbon monoxide is no longer absorbed by the reaction system, to produce acyl fluoride, wherein the step (a) is carried out in the absence of alcohol, and thereafter (b) a step of adding the alcohol to the reaction system and a step of reacting the acyl fluoride produced in the step (a) with the alcohol to produce the ester.
