The synthesis of 1-halonaphthalenes by the Cu-catalyzed benzannulation reaction of 2-(phenylethynyl)benzaldehyde and alkynes in the presence of the halogen reagents such as NBS, NCS, and NIS, was developed. This protocol afforded various type of 1-halonaphthalenes in moderate to excellent yields and the cross coupling reactions of 1-bromo-2-phenylnaphthalene prepared by this method with various reagents
的通过的2铜催化的苯并环化反应1-halonaphthalenes合成- (苯基乙炔基)苯甲醛和在卤试剂如NBS,NCS,和NIS的存在炔,被开发。该方案以中等至优异的产率提供了各种类型的1-卤代萘,并且通过该方法制备的1-溴-2-苯基萘与各种试剂的交叉偶联反应发生,从而给出了相应的1,2-二取代的萘。
