选择了异丙醇羧酸铝催化2-(2-甲基烯丙氧基)苯酚合成呋喃酚|探讨异丙醇羧酸铝用量对合成呋喃酚反应的影响. 实验结果表明, 异丙醇羧酸铝可高效催化2-(2-甲基烯丙氧基)苯酚合成呋喃酚. 当催化剂为异丙醇二乙酸铝, 用量为2-(2-甲基烯丙氧基)苯酚的2.50%(物质的量比), 呋喃酚的收率达到80.8%, 高于目前工业上以异丙醇铝为催化剂的78.3%, 具有应用价值.

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
