Synthesis of Isoquinolines Using Copper Nanoparticles Supported on Carbon Microsphere Cu-NP/C/PEG-400 as Heterogeneous Reusable Catalyst
Keywords:
Green synthesis, Heterogeneous catalyst, Cu-NP/C, Biodegradable solventAbstract
A new, eco-friendly method for synthesizing 1-Phenyl Isoquinoline derivatives has been developed using Cu-NP/C/PEG-400 as a heterogeneous, reusable catalyst. This method involves the activation of C-H and N-N bonds in 1-(diphenylmethylene) hydrazine and substituted aryl acetylenes. The process utilizes Cu-NP/C as an oxidant and AgSbF6 as an additive, all within a biodegradable PEG-400 solvent. This approach offers several advantages, including a straightforward extraction procedure, high atom economy, a wide substrate scope, and high product yields, making it an efficient and sustainable protocol for producing isoquinoline derivatives.
