Syntheses and structural characterization of 1-(4-Phenyl-2-thiazolyl)-3-(4- methylphenyl)- 5-(2-furyl)-4,5-dihydro-(1H)-pyrazole and 1-(4-(4-fluoro)phenyl- 2-thiazolyl)-3-(4-methylphenyl)- 5-(2-furyl)-4,5-dihydro-(1H)-pyrazole

Abstract

The title compounds were synthesized and characterized by IR, 1H-NMR, Mass and elementary analysis and single-crystal X-ray diffraction. In 1a, intermolecular C-H?? interactions produce a three-dimensional network. In 1b, intermolecular C-H?O hydrogen bonds generate an R22(22) ring. The hydrogen bonding is supported by C-H?? interactions.
