Abstract
Worm-like nanowires are among the most active nanomaterials. In this study, we report the synthesis of dibenzylamine (DBA) motifs from reductive amination of either aldehydes or nitriles catalyzed by entirely new worm-like PtMo nanowires (PtMo WNWs). Under the assistance of H2 gas, PtMo WNWs can be prepared in a facile manner, following which, their structure and composition are characterized by TEM, XRD, XPS, etc. Upon careful optimization of reaction parameters, the as-prepared PtMo WNWs work effectively in the activation of dihydrogen molecules, and both aldehydes and nitriles can be used as starting materials to fabricate DBAs under mild and green conditions. The reaction kinetics has been investigated, which reveals that the PtMo WNWs show superior activity in the conversion of imines into amines. This study provides a practical advancement in the preparation of amines. Moreover, the protocol reported herein is feasible for the synthesis of worm-like nanostructures with designed composition for various catalytic applications.
Highlights
Dibenzylamine (DBA) motifs are important compounds with extensive applications in rubber compounds, ne chemicals, corrosion inhibitors, and drug formulations;[1,2,3,4] in this regard, the development of methods allowing the selective synthesis of DBA is of great signi cance in organic chemistry
The PtMo worm-like PtMo nanowires (WNWs) were prepared through co-reduction of Pt and
Due to the highly efficient catalytic performance of PtMo WNWs in the reductive animation of the aldehyde under H2 gas, we examined the catalytic capability of PtMo in the reductive hydrogenation of nitriles (Table 2)
Summary
Dibenzylamine (DBA) motifs are important compounds with extensive applications in rubber compounds, ne chemicals, corrosion inhibitors, and drug formulations;[1,2,3,4] in this regard, the development of methods allowing the selective synthesis of DBA is of great signi cance in organic chemistry. Through signi cant research efforts made in this direction, synthetic routes, such as direct base-promoted mono-N-alkylation[5] or alkylative amination,[6,7] have been developed for the synthesis of DBA motifs. Problems such as the use of expensive starting materials, tedious workup procedures, low selectivity, and formation of large amounts of wasteful salts still remain to be addressed. The as-prepared nanowires work effectively in the activation of dihydrogen, following which, DBAs can be obtained from the reductive amination of either benzaldehyde (BzH) or benzonitriles (BzN) under mild and green reaction conditions (Scheme 1). Nanostructured catalysts, providing a much more practical pathway for catalytic applications
