Cerium chloride heptahydrate; ethyl lactate; green solvent; chalcones; 1, 3, 5-Triaryl-2-pyrazoline.

1,3,5-triaryl-2-pyrazoline derivatives were synthesised by a condensation reaction between chalcones and phenyl hydrazine using cerium chloride heptahydrate as a catalyst. All these reactions were carried out in ethyl lactate (70%) as a green solvent. Easy and efficient work up, recyclability of solvent andcatalyst are the key merits of this protocol.
