摘　　要：本文报道了用I2/NaNO2/4-OH-TEMPO为催化剂,空气为氧化剂,在冰乙酸中催化氧化苄醇的方法.文中考察了催化剂各组分和温度对催化氧化反应的影响,在催化过程中碘替代过渡金属作为4-OH-TEMPO的共催化剂,在选择条件下苄醇氧反应的产物产率达到90%,在反应过程中生成醛或酮.An efficient aerobic oxidation of alcohols to corresponding aldehydes or ketones by the catalyzed system of I2/NaNO2/4-OH-TEMPO in the presence of acetic acid was investigated.The influence of each component and the amount of catalyst were studied.Iodine is used as co-catalyst instead of metal in the reaction.Aerobic oxidations of benzylic alcohols were almost completed under optimized conditions and the product with yield of 90% can be obtained.
