本文报道了以2-烷基蒽醌为原料,结晶硫酸铜为催化剂,锌粉为还原剂于浓氨水(25%～28%)中一步法制备2-烷基蒽.产物通过硅胶柱层析,收率范围:55%～90%.文中从取代基的电子效应和空间位阻角度分析了产率的变化规律.同时考察了其它几种无机盐用作催化剂的催化作用.
In this paper, 2-alkylanthraquinone as raw material, crystal copper sulfate as catalyst and zinc powder as reductant in concentrated aqueous ammonia (25% ~ 28%) were prepared by one-step method of 2-alkylanthracene. The product was purified by silica gel column chromatography , The yield range: 55% ~ 90% .In this paper, the change law of the yield was analyzed from the perspective of the electronic effect and the steric hindrance of the substituents.At the same time, the catalytic effect of several other inorganic salts as catalysts was also investigated.
