Spectroscopic studies of aryl substituted 1-phenyl-2-pyrazolines: Steric and electronic substitution effects
A series of aryl substituted 1-phenyl-2-pyrazolines containing electron-donating and electron-withdrawing substituents on different positions of the C3– or C5-aryl groups were synthesized and their steric and electronic effects on ch
Solvent free synthesis of substituted-2-pyrazolines using imidazolium based ionic liquid as a solvent and catalyst: A green route approach
A series of substituted-2-pyrazolines synthesized using imidazolium based ionic liquid, 1,2-[bis-(3'-methyl-imidazolium-hydrogen sulphate)]-ethane as a solvent and catalyst, by reacting chalcones react with phenyl hydrazine. The compounds were characteriz

REGIOCHEMISTRY OF THE CYCLOADDITIONS OF DIPHENYLNITRILIMINE TO COUMARIN, 3-ETHOXYCARBONYL AND 3-ACETYL COUMARINS. A REINVESTIGATION
The cycloaddition reactions of diphenylnitrilimine to coumarin, 3-ethoxycarbonyl and 3-acetylcoumarins were studied.The observed regiochemistry of the reaction with the coumarin 4a was the same as the one suggested by other researchers.For the coumarins 4
