Green One-Pot Synthesis of Benzimidazoles from Dinitroarenes in Water Using a Ru-Doped Co-Based Heterogeneous Catalyst.

ABSTRACT: A novel methodology is presented for preparing non-noble metal-based heterogeneous catalysts doped with low amounts of noble metals, yielding highly active and reusable materials for sustainable organic transformations. A new Co-Ru@C catalyst was developed by incorporating small ruthenium nanoparticles (1 wt %) and cobalt nanoparticles (10 wt %) on Vulcan carbon via pyrolysis of a ruthenium-doped cobalt metal-organic framework supported on carbon (2D-Co-(Ru)-MOF/C). Advanced characterization (in situ PXRD and XAS, HAADF-STEM, HRTEM) confirmed strong Co-Ru interactions, enhancing catalytic activity. The catalyst was evaluated in the one-pot reductive amination of dinitrobenzenes to benzimidazoles using molecular hydrogen and water, which is in line with green chemistry. The sy
