One-Pot Preparation of Carbon Immobilized Nano-Metal Catalysts from Biomass

Preparation of carbon supported nanometal catalysts were realized through the carbonization of metal precursor doped carboxymethyl cellulose under nitrogen condition. This carbon supported nanometal catalyst exhibited good activity in the reductive amination of amine. The results suggested a promising one-pot route based on economical and sustainable biomass towards the development of value carbon materials as effective catalyst for C-N bond synthesis reaction.

Dibenzylamine motifs are an important class of crucial organic compounds and are widely used in fine chemical and pharmaceutical industries. The development of the efficient, economical, and environmentally friendly synthesis of amines using transition metal-based heterogeneous catalysts remains both desirable and challenging. Herein, we prepared the covalent organic framework (COF)-supported heterogeneous reduced COF-supported Pd-based catalyst and used it for the one-pot reductive amination of aldehydes. There are both Pd metallic state and oxidated Pdσ+ in the catalysts. Furthermore, in the presence of the reduced COF-supported Pd-based catalyst, many aromatic, aliphatic, and heterocyclic aldehydes with various functional groups substituted were converted to their corresponding amines products in good to excellent selectivity (up to 91%) under mild reaction conditions (70 °C, 2 h, NH3, 20 bar H2). This work expands the covalent organic frameworks for the material family and its support catalyst, opening up new catalytic applications in the economical, practical, and effective synthesis of secondary amines.
