A novel and efficient one‐pot procedure has been described for synthesis of 2,4‐disubstituted thiazoles and oxazoles from substituted ketones using phenyltrimethylammoniumtribromide as in situ brominating agent followed by reaction with thioamide/thiourea and amides/ureas, respectively in [bmim][BF4] ionicliquid. The advantages of the procedure include avoiding the handling of lacrymetric compounds
已经描述了一种新颖有效的单罐方法,该方法使用苯基三甲基三溴化铵作为原位溴化剂,然后分别与硫代酰胺/硫脲和酰胺/脲在[bmim]中反应,从取代的酮合成2,4-二取代的噻唑和恶唑。BF 4 ]离子液体。该方法的优点包括避免处理漆料化合物,有害和有毒的有机溶剂,以及产品的良率或优良率。
