Abstract
The previously unknown 3-(4-chlorophenyl)-7,7-dimethyl-2-phenyl-3,3a,4,5,6,7-hexahydroindazole 6a and (4-halophenyl)-7,7-dimethyl-1-phenyl-4,5,6,7-tetrahydroindazoles 7a,b were synthesized by the reaction of 6-arylidene-2,2-dimethylcyclohexanones with phenylhydrazine in the presence of pyridine. The molecular and crystal structures of compounds 7a,b were determined by X-ray diffraction.
