Efficient synthesis of carbofuran phenol from 2-(2-methylallyloxy)phenol was achieved by using (RCO2)nAl(OPr-#em/em#)3-n as the catalysts. The effect of molar ratio of catalyst (RCO2)nAl(OPr-#em/em#)3-n/2-(2-methyl- lallyloxy)phenol on the yield was investigated. By employing (CH3CO2)2AlOPr-#em/em# as the complex catalyst, the yield of carbofuran phenol was improved to 80.8%, which was higher than that of 78.3% in commercial installa-tion.

Key words: (RCO2)nAl(OPr-i)3-n, carbofuran phenol, Claisen rearrangment, cyclization
