摘　　要：以铂负载的g-C_(3)N_(4)为催化剂,在光照条件下,实现了苄醇的氧化脱氢,提供了一种合成芳基甲醛的有效方法。反应在光照和Pt/g-C_(3)N_(4)催化的条件下进行,该反应不需要加热和加入任何氧化剂,避免了传统工艺中加热和使用污染性氧化剂,且该催化反应及后处理简捷安全。研究了多个条件对反应的影响,结果表明最佳反应条件为:乙腈/水(3 mL/5 mL)为溶剂,光功率为75 W,光波长为365 nm。原料转化率最高达到100%,目标产物的产率最高达到92%。The selective oxidation of benzyl alcohols was achieved by using g-C_(3)N_(4)-supported platinum as the catalyst under light irradiation,which provides an effective method for synthesizing arylformaldehydes.The reactions were performed under conditions of light irradiation and Pt/g-C_(3)N_(4) catalyst,and the present reaction did not require an addition of any oxidant,avoiding the use of traditional heating and polluting oxidants.The reaction process and the post-treatment are simple and safe.The obtained results showed that the optimal reaction conditions were as follows:acetonitrile/water(3 mL/5 mL)as the solvent,75 W light irradiation and 365 nm wavelength of light.The highest conversion of the raw material is 100%,and the highest yield of the target product is 92%.
