在探索3-戊烯腈氢氰化合成己二腈反应的机理过程中, 发现3-戊烯腈在零价镍体系中可能同时存在多个平衡反应, 在不外加氰化氢条件下, 3-戊烯腈可以生成甲基戊二腈和己二腈. 采用零价镍、膦配体和无水ZnCl2 组成的催化体系研究了该反应过程, 考察了反应温度和配体的影响, 并采用原位红外对反应进行监测, 提出了可能的反应机理.

关键词: 零价镍, 3-戊烯腈, 2-甲基戊二腈, 己二腈, 反应平衡

The equilibrium reaction of 3-pentenenitrile was carried out in the system containing Ni(0), P-ligand and anhydrous ZnCl2. The equilibrium state of 3-pentenenitrile was affected by factors such as reaction temperatures and different ligands, which were investigated. The FTIR-ATR was used to monitor the reaction process of 3-pentenenitrile turning into 2-methylglutaronitrile and adiponitrile in absence of HCN and the possible reaction mechanism was proposed.

Key words: zero-valent nickel, 3-pentenenitrile, 2-methylglutaronitrile, adiponitrile, reaction equilibrium
