Chitosan-supported copper as an efficient and recyclable heterogeneous catalyst for A3/decarboxylative A3-coupling reaction. Tetrahedron Letters, 59(21), 1986-1991. doi: 10.1016/j.tetlet.2018.03.05340403910.1016/j.tetlet.2018.03.053http://10.2.3.109/handle/32116/1268Chitosan-supported copper (chit@copper) based heterogeneous catalysts have been explored for A3-coupling and decarboxylative A3-coupling. The developed protocol employs low catalyst loading, solventless condition and easy work-up for the synthesis of diversely substituted propargylamines. More importantly, the catalyst could be recovered and reused without any significant loss in the activity. This offer huge advantages as recyclability issues are rarely addressed in decarboxylative A3-coupling. Leaching studies were carried out using AAS and ICPMS analysis. It is envisaged that chit@copper catalysts can have potential applications in terms of efficiency and recyclability in the emerging area of decarboxylative C?H bond activation/functionalization strategies. ? 2018 Elsevier Ltden-USCarbonChitosanCopperHydrogen CatalystChemical BondDecarboxylationInductively Coupled Plasma Mass SpectrometryLeachingProcess DevelopmentReaction AnalysisStructure AnalysisSynthesisArticlehttps://www.sciencedirect.com/science/article/pii/S0040403918303678?via%3Dihub
