Outline of Final Research Achievements

The aim of this study was to develop alloy catalysts for the hydrogenation of nitriles that enable the production of different products in a single catalyst system. The catalytic activity was improved by alloying Pd, Rh and Pt which are selective for primary amines, secondary imines and secondary amines, respectively. Furthermore, the concentration of the corresponding metals in alloy catalysts enabled the selective synthesis of the respective products. This study has led to the development of Rh-Pd-Pt alloy catalysts for the selective production of primary amines, secondary imines and secondary amines by adjusting the metal composition.

Academic Significance and Societal Importance of the Research Achievements

ニトリルの水素化を含め，複数の生成物を与える化学反応において1つの触媒系で生成物を作り分けるための学理は構築されていない．反応選択性のスイッチングにより触媒プロセスの簡略化と低コスト化にも繋がるため，本研究は学術と社会の両面において科学の発展に貢献するものである．
