Synthesis of pyridinium ionic liquids.
Over the centuries, these privileged scaffolds have played an intriguing role in a wide range of research topics and, thus, this review aims at highlighting the pyridinium salts in terms of their synthetic routes, reactivity and their importance as pyridinium ionic liquids, as pyridinium ylides, as anti-microbial, anti-cancer, anti-malarial and.
The synthesis of a novel class of fluorous ionic liquids was investigated. The 2,6- dip erfluoroalkyl-substituted pyridinium salts f were solids at ambient temperature 2b - and insoluble in perfluoromethylcyclohexane.

Imidazolium and pyridinium ionic liquids from mandelic acid derivatives: Synthesis and bacteria and algae toxicity evaluation.
Ionic liquid supported synthesis (ILSS) has been successfully applied for a number of organic reactions like 1,3-cycloadditions, Knoevengeal reaction, Suzuki coupling, synthesis of thiazolidinones, oligosaccharide synthesis, and Grieco’s multicomponnet synthesis of tetrahydroquinolines.
The pyridinium-based ionic liquid is an ionic liquid containing a pyridinium cation. The stability, reactivity and catalysis in organic synthesis make them widely available. Pyridinium ionic liquids can be applied in Diels-Alder reaction, Friedel-Crafts reaction, Suzuki reaction, Grignard Reaction and the synthesis of some pharmaceutical agents.
Ionic liquids were originally well known as mixed of inorganic counter anions and organic counter cations derived from nitrogen heterocyclic compounds (, ). Nitrogen containing heterocyclic molecules constitutes the largest portion in ionic liquids synthesis.
The electronic energy levels and their populations were obtained for the pyridinium-based. ionic liquids, (PY)(Cl), (PY)(BF4), (PY)(N(CN)2), with density functional theory (DFT) using. the BLYP functional. BLYP is a well-established, reliable exchange-correlation functional in the. generalized gradient approximation.
