Ionic liquids have shown good catalytic performance and been widely used in the biomass conversion process due to their unique properties, including environmental friendship, low toxicity, and simple preparation In this work, a series of novel piperidinium-based ionic liquids were synthesized under mild conditions via a simple protonation reaction or nucleophilic substitution reaction. Among them, 4,4′-(propane-1,3-diyl)bis(1-(carboxymethyl)piperidin-1-ium) chloride ([PDCMPi]Cl) displayed the best catalytic performance. The highest yield (42.81 %) of 3A5AF from NAG was obtained after reacting in N-methyl-pyrrolidone (NMP) in the presence of piperidinium-based ionic liquids at 180 °C for 20 min under normal atm. conditions. Addnl., ionic liquid [PDCMPi]Cl showed good catalytic activity in six repeated catalytic runs. Meanwhile, a possible reaction pathway was also proposed on the basis of the results of NMR spectra. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Recommanded Product: 628-13-7).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Recommanded Product: 628-13-7
