重铬酸钾是多种有机物氧化的重要试剂.由于重铬酸钾在水及有机溶剂中的溶解度很小,所以常采用它的硫酸溶液作反应试剂.然而,这一方法不适用于对酸敏感的化合物的氧化,而且在氧化伯醇成醛时常伴有羧酸的生成.最近,我们报道了一种新选择性氧化试剂——重铬酸双三乙基苄铵.它可由氯化三乙基苄铵与等当量的三氧化铬在稀酸中反应制得.它的特点是能溶于多种有机溶剂中,可使多种氧化反应能在有机溶剂中顺利进行.前文我们已经报道,它在中性条件下可使苄醇或烯丙基醇选择氧化成相应的羰基化合物.硫醇或硫酚选择氧化成二硫化物.本文将继续扩大这一新试剂的应用 Potassium dichromate is an important reagent for the oxidation of many organic compounds.Due to the low solubility of potassium dichromate in water and organic solvents, sulfuric acid solution is often used as reaction reagent.However, this method is not suitable for acid Sensitive compounds oxidation, but also in the oxidation of primary alcohols into aldehydes often accompanied by the formation of carboxylic acid.We recently reported a new selective oxidation reagent - bis-triethylammonium dichromate, which can be three Ethylbenzylammonium with an equivalent of chromium oxide in dilute acid in the reaction of its system is characterized by its ability to dissolve in a variety of organic solvents, can make a variety of oxidation reactions can be carried out smoothly in organic solvents.We have previously reported , Which selectively oxidizes benzyl alcohol or allyl alcohol to the corresponding carbonyl compound under neutral conditions. The selective oxidation of thiol or thiophenol to disulfide will continue to expand the application of this new reagent
