dihalo 1,3-thiazole derivatives can be efficiently and selectively prepared under mild conditions from 2-amino-1,3-thiazoles. Halogenations proceed easily in the presence of copper(I) or copper(II) chlorides, bromides, or iodides directly in solution or with supported copper halides.
单卤和二卤 1,3-噻唑衍生物可以在温和条件下由 2-氨基-1,3-噻唑高效且选择性地制备。在铜 (I) 或铜 (II) 氯化物、溴化物或碘化物直接存在于溶液中或与负载的卤化铜一起存在时,卤化很容易进行。
