Example 1 was repeated except phenylacetylene ##STR9## was employed as the sole alkyne (25 mmols); the amount of CuI was increased to 0.25 mmol; and the reaction temperature was increased to 56° C. After 24 hours, the bromonitrobenzene was totally converted, giving an 84% yield of phenyl-3-nitrophenylacetylene ##STR10## Example 16 shows that it is not predictable (when Ex. 16 is compared with Exs. 13-15) which charge stocks will react with which halogenated arenes.
