摘 要:本文选用商品化的大孔型弱碱性阴离子交换树脂作载体制得聚合物负载的铬(Ⅵ)氧化剂,用它氧化各种醇生成醛和酮。还研究了反应温度,溶剂对氧化反应的影响。结果表明,位阻小的醇比位阻大的醇易氧化;烯丙基和苄基醇比直链饱和醇易氧化。This paper describes the studies on synthesizing an oxidizing reagent by a commercial macroporous weak basic anion-exchange resin (abbrev. WBER) bound with chromium (Ⅵ) and using this oxidizing reagent to oxidize many kinds of alcohols to aldehydes or / and ketones. The authors also studied the influence of the reaction temperature and solvents to the oxidizing reactions. The alcohols with smaller steric hindrance are oxidized more easily than those having larger steric hindrance. e.g.allylic and benzylic alcohols are easily oxidized than normal saturated alcohols.
