α,β-不饱和醛主要合成路线是氧化对应的α,β-不饱和醇。使用的氧化剂有琼斯试剂、科林试剂、特丁基铬酸酯、吸附在阴离子交换树脂上的铬酸、四正丁基铵的铬酸盐和水合二铬酸锌。但是这些试剂多数有缺点,大部分需要比较激烈的反应条件。吸附在硅胶上的铬酸(H_2CrO_4/SiO_2)是氧化对应的醇合成饱和醛的有效试剂。浙江医 The main synthetic route of α, β-unsaturated aldehydes is the oxidation of the corresponding α, β-unsaturated alcohols. Oxidants used are Jones reagent, colin reagent, t-butyl chromate, chromic acid adsorbed on anion exchange resin, tetra-n-butylammonium chromate and hydrated zinc dichromate. However, most of these reagents have disadvantages, most of which require more intense reaction conditions. Chromic acid (H_2CrO_4 / SiO_2) adsorbed on silica gel is an effective reagent for the oxidation of the corresponding alcohols to synthesize saturated aldehydes. Zhejiang Medical
