苄醇衍生物与K3PO4、过氧叔丁醇(TBHP,70%水溶液)在DMSO中,8-羟基喹啉铜络合物(20 mol%)和碘化四丁铵(TBAI,40 mol%)催化下,120℃反应24 h,生成相应的羧酸甲酯,甲基由TBHP中C-C键断裂提供,8例收率53%~92%。若以芳香醛为底物时,反应无需加入K3PO4,14例收率61%~96%,芳环取代基团的电性和位阻对反应影响不大。[黄火明摘] Benzyl alcohol derivatives were mixed with K3PO4, t-butyl hydroperoxide (TBHP, 70% in water) in a mixture of 8-quinolinol copper complex (20 mol%) and tetrabutylammonium iodide (TBAI, 40 mol% Under the catalysis, the reaction was carried out at 120 ° C for 24 h to yield the corresponding methyl carboxylate. The methyl group was cleaved by the CC bond in TBHP and the yield of 8 was 53% -92%. If the aromatic aldehyde as a substrate, the reaction without adding K3PO4, 14 cases of yield of 61% to 96%, the aryl ring substituent groups of electrical and steric hindrance little effect on the reaction.
