allowed to react with diphenyldiselenide in the presence of copper(II) bromide, bromophenylselenation of the carbon–carbon triple bond smoothly proceeded to give the corresponding β-bromo alkenyl phenyl selenides in moderate to good yields. Similarly, chlorophenylselenation of alkynes occurred by the use of copper(II) chloride as a copper salt giving β-chloro alkenyl phenyl selenides in good yields.
当炔烃在溴化铜 (II) 存在下与二苯基二硒化物反应时,碳-碳三键的溴苯基硒化顺利进行,以中等至良好的产率得到相应的 β-溴烯基苯基硒化物。类似地,炔烃的氯苯基硒化是通过使用氯化铜 (II) 作为铜盐而发生的,从而以良好的产率得到 β-氯烯基苯基硒化物。
