significance of such pioneering reactions. Due to the markedly polar attributes and insolubility of the resulting products in water, facile separation from the reaction milieu is facilitated through the introduction of water into the reaction mixture. Consequently, this specific ionic liquid methodology provides an uncomplicated and selective avenue for the synthesis of compounds possessing noteworthy
涉及苯甲醇或卤化苄与脲的反应,在包含氯化胆碱和硝酸铝离子液体的混合物作为溶剂中进行,导致N-单取代脲产物的合成。该反应在指定的反应条件下显示出苯甲醇和苯甲基卤化物的各种衍生物的优异产率。当卤代苯和苯甲醇在制备的离子液体存在下与尿素发生反应时,观察到唯一的选择性途径,从而产生相当大的N-单取代尿素产物产率。这种方法具有多种优点,包括反应选择性、产品效率高、产品易于分离、溶剂对环境无害以及无需使用昂贵且危险的催化剂。这些属性强调了此类开创性反应的重要性。由于所得产物具有明显的极性属性且不溶于水,因此通过将水引入反应混合物中可以促进与反应环境的轻松分离。因此,这种特定的离子液体方法为合成具有显着制药和工业用途的化合物提供了一种简单且选择性的途径。 图形概要
