Résumé : | A simple, efficient, cheap and broadly applicable system for the carboxylation of benzylic bromides with carbon monoxide and water is reported. Upon simple reaction with only 2.5 wt% of Pearlman’s catalyst and 10 mol% of TBAB in THF at 110 °C for 4 hours, a range of benzylic bromides can be smoothly converted to the corresponding arylacetic acids in good to excellent yields after simple extraction and acid-base wash. The reaction was found to be broadly applicable, scalable and could be successfully extended to the use of ex situ-generated carbon monoxide and applied to the synthesis of the non-steroidal anti-inflammatory drug diclofenac. |
