以廉价无污染的FeCl_3/H_2O_2作为化苄基叠氮转化为苯甲醛的氧化体系,考察了氧化剂种类、氧化剂用量以及底物种类等因素对费用的影响。实验结果表明,采用H_2O_2做氧化剂,FeCl_3 10mol%,n(叠氮)∶n(H_2O_2)=1∶2,在回流的条件下,苯甲醛的产率可以达到93%,不同种类的苄基叠氮都具有很好的相容性。该方法绿色、无污染,反应条件温和,价格低廉,为苯甲醛的合成提供了新的思路。 The cheap and pollution-free FeCl_3 / H_2O_2 was used as the oxidation system of benzalzyl azide to benzaldehyde. The effects of oxidant type, oxidant dosage and substrate type on the cost were investigated. The experimental results show that the yield of benzaldehyde can reach 93% under the condition of reflux with H_2O_2 as oxidant, 10 mol% FeCl_3 and n (H_2O_2) = 1: 2. Different kinds of benzyl groups Nitrogen has good compatibility. The method is green, pollution-free, mild reaction conditions and low price, and provides a new idea for the synthesis of benzaldehyde.
