Ionic liquid: an efficient and recyclable medium for synthesis of unsymmetrical diorganyl selenides promoted by InI.
In an environmentally friendly protocol, InI was used as a reducing agent for the Se-Se bond to prepare unsymmetrical diorganyl selenides with very short reaction times, mild conditions and excellent yields using (bmim)BF(4) as a recyclable solvent.
متن کاملA green protocol for synthesis of pyran annulated hetrocyclic systems using Na2SO4 as an efficient catalyst
Na2SO4 as an inexpensive and effective catalyst has provided a green protocol for the synthesis of tetrahydrobenzo[b]pyran, pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2c]chromene derivatives from the three-component domino reaction of aromatic aldehydes and malononitrile with 4-hydroxycoumarin/ dimedone/ barbituric acid in ethanol/water as a mixture of solvent that, this mixture entirely is ...

متن کاملIron-catalysed aziridination reactions promoted by an ionic liquid.
A catalytic system based on iron(II) triflate, quinaldic acid and an ionic liquid allows the aziridination of olefins with equimolar amounts of iminoiodinane providing products in good to moderate yields.
متن کاملBasic Task-specific Ionic Liquid as Catalyst and Reaction Medium: A Green Protocol for the Synthesis of 4-Oxo-6-aryl-2-thioxo-1,2,3,4- tetrahydropyrimidine-5-carbonitrile Derivatives
Abstract A novel basic ionic liquid based on imidazolium cation is designed, synthesized and successfully used as a catalyst for the one-pot synthesis of 4-Oxo-6-aryl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carbonitrile derivatives. The remarkable features of this new catalyst are its ethyleneoxy bridge which participates in dissolving organic compound in the ionic liquid and its strong base co...
