Abstract

Interconnected ruthenium dioxide nanoparticles (RuO₂NPs) anchored graphite oxide nanocatalyst (RuO₂/GO) with good BET surface-area (285 m²/g) was prepared. Under feasible reaction conditions, the RuO₂/GO worked well for oxidative synthesis of imines. The RuO₂/GO catalyzed a broad range of amines including less reactive aliphatic amines in good yields (98–58%) with excellent selectivity (100%). This is the most efficient RuO₂-based nanocatalyst for the synthesis of imines among those reported to date. An indirect two-step method was adopted for the coupling of alcohols and amines, and the results found to be excellent. The reusability, stability and heterogeneity of RuO₂/GO were also investigated.
