Amines are key intermediates in the chemical industry. Due to their nucleophilic properties, they impart high reactivity . Various amines, including primary, secondary, and tertiary amines, are widely used to produce agrochemicals, pharmaceuticals, dyes, and polymers . Primary amines, in particular, are important raw materials for manufacturing drugs, pesticides, emulsifiers, and plasticizers . Currently, the methods for synthesizing primary amines include reductive amination of carbonyl compounds , hydrogenation of nitro compounds , amination of alcohols , reduction of nitrile compounds , and N-alkylation of halogenated compounds . Among them, the catalytic hydrogenation of nitrile compounds using molecular hydrogen as a reducing agent has the advantages of high atom economy and a simple process and is a popular choice for the industrial synthesis of amine compounds . However, nitrile hydrogenation also has disadvantages. The hydrogenation mechanism is complex as shown in Fig 1 . The by-products include partially hydrogenated nitrile compounds, also known as imines, and condensation side reactions with other nucleophilic substances such as substrates in the hydrogenation system to form secondary and tertiary amines , resulting in the problem of low selectivity of the amination product in the reaction . It is still a huge challenge to obtain primary amines with high selectivity.
