溴酸钠和氯化铁为助催化剂2,2,6,6-四甲基-N-氧化哌啶催化醇的氧化
摘要:
建立了溴酸钠和氯化铁为助催化剂2,2,6,6-四甲基-N-氧化哌啶(NaBrO3-FeCl3-TEMPO)新型催化体系,以苯甲醇的氧化为研究对象,得出各成分与底物的最佳物质的量比为:2% TEMPO、35% NaBrO3、3.7% H2SO4、2% FeCl3·6H2O。该体系在室温下可有效实现芳香醇、脂肪醇及杂环醇的氧化,收率高(99%)、选择性强(99%),在无氧条件下,仍表现出较好的催化活性。

Catalyzed Oxidation of Alcohols by 2, 2, 6, 6-Tetramethyl-1-iperidinyloxy with Sodium Bromate and Ferric Chloride as Accelorators
Abstract:
A 2,2,6,6-tetramethyl-1-piperidinyloxy catalytic system with sodium bromate and ferric chloride as accelorators(NaBrO3-FeCl3-TEMPO) was developed for efficient oxidation of alcohols. Taking example for benzyl alcohol,the molar ratios of TEMPO,NaBrO3,H2SO4,FeCl3·6H2O relative to the substrate are optimized at 2%,35%,3.7% and 2%,respectively. Aromatic alcohol,aliphatic alcohol and heterocyclic alcohol can be effectively oxidized to the corresponding carbonyl compounds with high yields up to 99% and selectivity up to 99% at room temperature even under anaerobic conditions.
