A novel reaction of α-halo ketone (α-bromo and α-chloro ketone) with irradiation under microwave gave the corresponding α-hydroxyketone and pyrazine derivative in good yields. In the case of α,α′-dibromo ketone, α-diketone was obtained. This reaction affords a new, clean and convenient synthetic method for α-hydroxyketone, α-diketone, α-chloro ketone and pyrazine derivative.
微波辐射下α-卤代酮(α-溴代和α-氯代酮)的新型反应可得到相应的α-羟基酮和吡嗪衍生物,收率很高。在α,α′-二溴酮的情况下,获得了α-二酮。该反应为α-羟基酮,α-二酮,α-氯酮和吡嗪衍生物的合成提供了一种新的,清洁且方便的方法。
