allowed to react with diphenyl diselenide 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.
