中文摘要：

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.

英文摘要：

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.
