The reactions of acetylenes with bromine in alcohols at 20–25 °C afford dibromodialkoxyalkanes in good yields together with variable amounts of dibromoalkenes. Similar treatment of phenylacetylene with copper(II) bromide gives only bromophenylacetylene and 2-phenyl-1,1,2-tribromoethylene, the latter being formed by dibromination of the former with copper(II) bromide.
乙炔与溴在 20-25 °C 的醇中反应以良好的收率提供二溴二烷氧基烷烃和不同数量的二溴烯烃。用溴化铜 (II) 对苯乙炔进行类似处理,仅得到溴苯乙炔和 2-苯基-1,1,2-三溴乙烯,后者通过前者与溴化铜 (II) 的二溴化反应形成。
