3-selenadiazoles was achieved using an ionic liquid as a novel soluble support. Ionic liquid-supported sulfonyl hydrazine was synthesized and reacted with a number of ketones to afford the corresponding ionic liquid-supported hydrazones that were converted to 1,2,3-thiadiazoles in the presence of thionyl chloride. The reaction of ionic liquid-supported hydrazones with selenium dioxide in acetonitrile afforded
使用离子液体作为新型可溶性载体,可以方便地合成1,2,3-噻二唑和1,2,3-硒二唑。合成了离子液体负载的磺酰肼,并使其与多种酮反应,得到了相应的离子液体负载的,在亚硫酰氯的存在下将其转化为1,2,3-噻二唑。离子液体负载的azo与二氧化硒在乙腈中的反应得到1,2,3-硒代二唑。这种方法的优点是易于处理,简单的反应条件和高纯度。
