Herein, we describe a greener protocol for the one-pot synthesis of 3-Se/S-4-chromen-4-ones. The desired products were obtained in good to excellent yields using 2-hydroxyphenyl enaminones and half equivalents of various odorless diorganyl dichalcogenides (S/Se) in the presence of glycerol (5 molar equiv) and KIO (15 mol %) as the catalyst under solvent-free conditions.
在此，我们描述了一种更环保的一锅法合成3-硒/硫代-4-色满-4-酮的方法。在无溶剂条件下，使用2-羟基苯基烯胺酮和半当量的各种无味二有机二硫属元素化物（硫/硒），以甘油（5摩尔当量）和KIO（15摩尔%）作为催化剂，以良好至优异的产率获得了所需产物。
