(E)-3-(4-Chlorophenyl)-3-[3-(4-chlorophenyl)-1H-pyrazol-1-yl]prop-2-enal
In the title compound, C(18)H(12)Cl(2)N(2)O, the pyrazole ring is almost planar [r.m.s. deviation = 0.002 Å] while the two chloro-phenyl rings are twisted out from the plane of the pyrazole ring, making dihedral angles of 5.3 (1) and 65.34 (4)°. In the crystal, centrosymmetric R(2) (2)(24) dimers are formed about crystallographic inversion centres through a pair of C-H⋯Cl inter-actions. These d...

There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(18)H(12)Br(2)N(2)O. In each mol-ecule, one of the bromo-phenyl rings lies almost in the plane of pyrazole unit [dihedral angles of 5.8 (3)° in the first mol-ecule and and 5.1 (3)° in the second] while the other ring is approximately perpendicular to it [dihedral angles of 80.3 (3) and 76.5 ...

In the title mol-ecule, C20H18N2O3, the pyrazole ring forms a dihedral angle of 2.2 (1)° with its meth-oxy-phenyl substituent and a dihedral angle of 67.2 (1)° with the benzene substituent on the propenal unit. In the crystal, mol-ecules are connected by weak C-H⋯O hydrogen bonds, forming R 2 (2)(26) and R 2 (2)(28) cyclic dimers that lie about crystallographic inversion centres. These dimers a...

In the title compound, C(22)H(21)BrN(4)O(2)·H(2)O, the two pyrazole rings are essentially planar [maximum deviations 0.002 (1) and 0.002 (1) Å], and form a dihedral angle of 73.46 (9)°. The dihedral angle between the benzene rings is 29.33 (7)°. In the crystal, mol-ecules are connected via C-H⋯O and O-H⋯N hydrogen bonds, forming layers in the ab plane.

6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
