摘要:发展了一种新型、实用性的以溴化亚铜为催化剂,以1,8-二氮杂双环[5.4.0]十一碳-7-烯(DBU)为添加剂,在空气条件下进行氧气氧化苄醇的催化体系.各种一级或二级苄醇及烯丙醇可以以高的产率及选择性转换为相应的醛和酮.该过程为无溶剂反应,同时不需要使用四甲基哌啶氧化物(TEMPO)类助氧化剂.
A novel and practical cuprous bromide-catalyzed aerobic oxidation of benzylic alcohols with 1,8-diazabicyclo-[5.4.0]undec-7-ene(DBU) as the additive under air atmosphere has been developed. Various primary and secondary benzylic alcohols and allylic alcohols were smoothly transformed into the corresponding aldehydes and ketones with high yields and selectivity. The process is 2,2,6,6-tetramethylpiperidin-1-oxyl(TEMPO) free and solvent-free.
