某些硝基芳族羟基取代的乙炔在异质RuS2催化剂上的选择性加氢

Selective hydrogenation of certain nitroaromatic hydroxy substituted acetylenes over a heterogeneous RuS.sub.2 catalyst
摘要：
Nitroaromatic hydroxy substituted acetylene compounds wherein both the nitro and acetylene groups are directly connected to aromatic ring carbon atoms are hydrogenated in an inert solvent to selectively reduce the nitro function over a ruthenium disulfide catalyst. Of particular interest is the preparation of aminophenylacetylene from nitrophenyl hydroxy substituted acetylene.
摘要（中）：

其中硝基和乙炔基直接与芳香环碳原子连接的硝基芳族羟基取代的乙炔化合物在惰性溶剂中氢化以选择性地降低二硫化钌催化剂上的硝基官能团。 特别感兴趣的是由硝基苯基羟基取代的乙炔制备氨基苯乙炔。
