3-(4-Bromophenyl)-1-(4-chlorobenzyl)-1H-pyrazole-5-carbaldehyde

Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.036; wR factor = 0.104; data-to-parameter ratio = 15.8.The title compound, C 17 H 12 BrClN 2 O, was synthesized by oxidation of [3-(4-bromophenyl)-1-(4-chlorobenzyl)-1H-pyrazol-5-yl]methanol under mild conditions. The pyrazole ring makes dihedral angles of 3.29 (9) and 74.91 (4) , respectively, with the bromophenyl and chlorophenyl rings. Related literature
