PROBLEM TO BE SOLVED: To provide a process for producing an imine and an enamine in high yield by increasing the activity of hydroamination reaction of 1-alkyne. SOLUTION: An imine or an enamine is produced by reacting a 1-alkyne with a primary amine or a secondary amine in the presence of a ruthenium complex catalyst. The reaction system is added with HF, HBF4, HPF6, BF3.O(C2 H5)2 or a salt capable of generating HF, HBF4 or HPF6 in the reaction system. The ruthenium complex is preferably Ru3(CO)12. |
