organic compounds
The title compound, C22H20N6, was synthesized by the reaction of 5-amino-3-methyl-1-phenylpyrazole with [4-(dimethylamino)benzylidene]malononitrile in glycol under microwave irradiation. X-ray crystal structure analysis reveals that the molecules exist as centrosymmetric N—HN hydrogen-bonded dimers.
organic compounds
The title compound, C17H14ClN5O, was synthesized by the reaction of malononitrile with 4-chlorobenzaldehyde and morpholine in glycol under microwave irradiation. X-ray analysis reveals that the morpholine ring is in a chair conformation. In the crystal structure, intermolecular N—HO, C—HN and N—HN hydrogen bonds form a three-dimensional network.
organic compounds
The title compound, C22H20BrNO, was synthesized by the reaction of 4-bromobenzaldehyde with p-toluidine and 5,5-dimethylcyclohexane-1,3-dione in glycol under microwave irradition. The terminal saturated six-membered ring of the dihydroacridine moiety has a twist-boat conformation. The crystal packing is mainly stabilized by van der Waals forces.
