The addition of cyanogen bromide to an acetylenic bond was studied. Phenylacetylene reacted with cyanogen bromide in the presence of aluminum bromide to afford trans-β-bromocinnamonitrile. Similarly, p-bromo-and p-methoxyphenylacetylene, tolane and methylphenylacetylene yielded corresponding β-bromocinnamonitriles. Nevertheless, p-nitrophenylacetylene did not react with cyanogen bromide under the same conditions.
研究了溴化氰与乙炔键的加成反应。苯乙炔与溴化氰在溴化铝存在下发生反应,生成反式-β-溴肉桂腈。同样,对溴和对甲氧基苯乙炔、甲苯和甲基苯乙炔也能生成相应的 β-溴肉桂腈。然而,在相同条件下,对硝基苯乙炔没有与溴化氰发生反应。
