摘要

在氮气气氛下,以金属镍/锌/水/乙氢为催化剂体系,在大量锌粉和水的存在下,以高收率加氢制琥珀酸二乙酯。金属镍是氢化反应的活性物质,锌粉和水是生成氢的试剂。在此反应条件下,苄基苯胺加氢得到n -苯基苯胺,反应量适中,同时水解得到苯胺和苯甲醛。

金属ニッケル/亜鉛/水/エタノール触媒系による不飽和エステルの水素化反応
Under nitrogen atmosphere diethyl maleate was hydrogenated to give diethyl succinate in a high yield with metallic nickel/Zn/H2O/EtOH catalyst system in the presence of a large amount of zinc powder and water. Metallic nickel was an active species for the hydrogenation and zinc powder and water were reagents to produce hydrogen. Benzylideneaniline was hydrogenated to give N-phenylbenzylamine in a moderate yield under the reaction conditions and it was appreciably hydrolyzed to afford aniline and benzaldehyde at the same time.
