Abstract
Nine novel thiourea derivatives containing pyrazole rings have been prepared in good yields by the reaction of 5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)pyrazole with acylisothiocyanates, which were generated in situ by potassium thiocyanate and different acyl chlorides in one pot. N-Benzoyl-N‘-[1-(2,6-dichloro-4-trifluoromethyl)phenyl-3-cyano-1H-pyrazol-5-yl]thiourea was characterised by a single crystal X-ray diffraction study.
