大功率紫外- led照射(365 nm)可有效加速十钨酸盐阴离子催化苯甲醇1经苯甲醛2氧化生成苯甲酸3。随着紫外- led光功率的增加,苯甲酸的选择性和收率也增加。在2mol %的十钨酸盐阴离子催化下,反应在1 h内完成,产率为93%。流动光反应器和大功率辐照的结合将氧化反应加速到几分钟的时间间隔。
High-power UV-LED irradiation (365 nm) effectively accelerated the decatungstate-anion-catalyzed oxidation of benzyl alcohol 1 to benzoic acid 3 via benzaldehyde 2. As the power of the UV-LED light increased, both the selectivity and yield of benzoic acid also increased. The reaction was finished within 1 h to give 3 in a 93% yield using 2 mol% of decatungstate anion catalyst. The combination of a flow photoreactor and high-power irradiation accelerated the oxidation reaction to an interval of only a few minutes.
