a simple and environmentally benign procedure for the synthesis of 14-aryl-14h-dibenzo[a,j]xanthenes by a one-pot condensation of 2-naphthol with aromatic aldehyde in the presence of [et3nh][hso4] as an acidic ionic liquid catalyst under solvent-free conditions has been developed. the reaction work-up is very simple and the catalyst can be easily separated from the reaction mixture and reused s...

Brønsted acidic ionic liquids (BAILs) can play a dual role, as a solvent and as a catalyst, in many reactions. However, molecular details of the catalytic mechanism are poorly understood. We present here a density functional theory (DFT) study for the catalytic mechanism of the transesterification of methyl ester (ME) with trimethylolpropane (TMP), in the presence of three representative BAILs,...

Protic ionic liquids (PILs) are a subgroup of ionic liquids and easily formed by proton transfer from a Brønsted acid to a Brønsted base. Two new crystalline aluminophosphates, [C5H16N2][Al(PO4)(HPO4)] (AlPO-PIL1) and [C5H16N2][Al2(OH)2 (PO4)2] (AlPO-PIL2), are successfully prepared for the first time from a protic ionic liquid, 3-dimethylaminopropylamine acetate. Their structures were determin...

a simple and mild method for tetrahydropyranylation of alcohols is reported at room temperature using a catalytic amount of 3-methylimidazolinium hydrogensulfate([hmim]hso4) as a green, efficient and reusable catalyst. using solvent-free conditions, non-toxic and inexpensive materials, modest and clean work-up, short reaction times and high yields of the products are the advantages of this method.

A polymer gel electrolyte using AlCl3 complexed acrylamide as a functional monomer and acidic ionic liquid based on a mixture of 1-ethyl-3-methylimidazolium chloride (EMImCl) and AlCl3 (EMImCl-AlCl3, 1-1.5, in molar ratio) as a plasticizer has been successfully prepared for the first time via free radical polymerization. Aluminum deposition is successfully achieved using a polymer gel electroly...
