Sc. Shim et al., CARBONYLATION OF (DICHLOROMETHYL)BENZENE CATALYZED BY COBALT CARBONYLAND IRON CARBONYL UNDER PHASE-TRANSFER CATALYSIS, Bulletin of the Korean Chemical Society, 14(5), 1993, pp. 618-620
Treatment of (dichloromethyl)benzenes with CO (1 atm) in the presene o
f catalytic amount of Co2(CO)8, Fe(CO)5, and BTEAC under two phase sys
tems with NaOH(aq) and PhCH3 containing small amount of alcohol for 20
hours at 80-degrees-C gives phenylacetic acids in moderate yields.
