NOVELTY - Synthesizing tetramethyldiene triamine compound (I) comprises adding amine and raw material nitrile into the reactor using palladium-rhodium graphene as catalyst, heating at 90 degrees C under hydrogen atmosphere of 3-8 MPa, stirring for 2-6 hours, cooling to room temperature, centrifuging and separating the catalyst and the reaction liquid, distilling the reaction solution under reduced pressure to obtain final product. USE - The method is useful for synthesizing tetramethyldiene triamine compound. ADVANTAGE - The method: has simple process, recyclable catalyst, reactants conversion rate of more than 95%, and selectivity of more than 90%. DETAILED DESCRIPTION - Synthesizing tetramethyldiene triamine compound of formula (I) comprises adding amine and raw material nitrile into the reactor using palladium-rhodium graphene (palladium/rhodium-CDG) as catalyst, heating at 90 degrees C under hydrogen atmosphere of 3-8 MPa, stirring for 2-6 hours, cooling to room temperature, centrifuging and separating the catalyst and the reaction liquid, distilling the reaction solution under reduced pressure to obtain final product. m, n = 1 or 2.
