  A novel basic ionic liquid, 1-(2-aminoethyl)pyridinium hydroxide, containing both Brønsted base and Lewis base sites has been used as an efficient catalyst for the synthesis of 2-amino-4-phenyl-6-(phenylsulfanyl)-3,5-dicyanopyridines. The condensation and oxidation tandem reaction of aldehydes, malononitrile, and thiols, performed in aqueous ethanol, afforded reasonable to good yields within 30–60 min. After the reaction, the catalyst could be recycled and reused. A possible mechanism to account for the tandem reaction is proposed. .

  An efficient and greener protocol for the synthesis of poly functionalized pyridines using tetra‐n‐butyl ammonium fluoride (TBAF) in water is established. Remarkable advantages of the present synthetic strategy over the others are shorter reaction times, higher isolated yields, reuse of catalytic system, simple work‐up procedure and more especially its applicability to heteryl and aliphatic aldehydes
