Abstract A new complex, Co(MBTC) 2 (DMF) 2 (MBTC=6‐methoxybenzothiazole‐2‐carboxylate, DMF= N , N ‐dime‐ thylformamide), was synthesized in DMF solution and characterized by single crystal X‐ray diffraction analysis. Using the cobalt complex as catalyst, phenylacetic acid was prepared by the carbonylation of benzyl chloride with carbon monoxide (0.1 MPa). The effects of solvents, phase transfer catalysts and temperature on the reactions were investigated. The yield of phenylacetic acid was higher than 90% in optimized condition.
