3,5-Diphenyl-1-(quinolin-2-yl)-4,5-dihydro-1H-pyrazol-5-ol.

ABSTRACT: In the title compound, C(24)H(19)N(3)O, the pyrazole ring is close to being planar (r.m.s. deviation of the five fitted atoms = 0.062?Å), and each of the N-bound quinoline ring [dihedral angle = 9.90?(7)°] and the C-bound phenyl ring in the 3-position is close to being coplanar [dihedral angle = 8.87?(9)°]. However, the phenyl ring in the 5-position forms a dihedral angle of 72.31?(9)°. The hy-droxy group forms an intra-molecular hydrogen bond to the quinoline N atom. In the crystal, mol-ecules are connected into supra-molecular layers two mol-ecules thick in the bc plane by C-H?O and C-H?? inter-actions.

1,3-Diphenyl-4,5-dihydro-1H-pyrazol-5-one.

Project description:In the title pyrazolone derivative, C(15)H(12)N(2)O, the five-membered ring is approximately planar (r.m.s. deviation = 0.018 Å), and the N- and C-bound benzene rings are inclined to this plane [dihedral angles = 21.45 (10) and 6.96 (10)°, respectively] and form a dihedral angle of 20.42 (10)° with each other. Supra-molecular layers are formed in the crystal structure via C-H⋯O and C-H⋯N inter-actions, and these are assembled into double layers by C-H⋯π and π-π inter-actions between the pyrazole and C-bound benzene rings [ring centroid-centroid distance = 3.6476 (12) Å]. The double layers stack along the a axis being connected by π-π inter-actions between the N- and C-bound benzene rings [ring centroid-centroid distance = 3.7718 (12) Å].

Project description:In the title compound, C(17)H(14)Cl(2)N(2)O, the dihedral angles between the pyrazole ring and the mean planes of the benzene and chloro-substituted benzene rings are 75.97?(1) and 16.63?(1)° respectively. In the crystal, two weak C-H?O inter-molecular hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.774?(4) and 3.716?(7)?Å] are observed.

1-[3,5-Bis(4-fluoro-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]ethanone.

Project description:In the asymmetric unit of the title compound, C(17)H(14)F(2)N(2)O, there are three independent mol-ecules (A, B and C) which differ slightly in the relative orientations of the two fluoro-phenyl rings. In mol-ecules A and C one of the fluoro-phenyl rings is disordered over two positions, with occupancy ratios of 0.72 (2):0.28 (2) for mol-ecule A and 0.67 (2):0.33 (2) for mol-ecule C. The dihedral angle between the two fluoro-phenyl rings in the independent mol-ecules lie in the range 70.3 (3)-84.0 (3)°. In the crystal structure, the mol-ecules are linked via inter-molecular C-H⋯O and C-H⋯F hydrogen bonds and π⋯π stacking inter-actions [centroid-centroid distance = 3.7508 (13) Å], forming a three-dimensional network.

1-Benzoyl-3,5-diphenyl-4,5-dihydro-1H-pyrazole.

Project description:In the title compound, C(22)H(18)N(2)O, the pyrazole ring is almost planar (r.m.s. deviation = 0.0098 Å) and its mean plane makes dihedral angles of 62.2 (2), 87.2 (2) and 8.0 (2)° with the phenyl and benzoyl rings, respectively. The crystal packing is stabilized by π-π stacking inter-actions [centroid-centroid distance = 3.658 (2) Å] and weak inter-molecular C-H⋯O hydrogen bonds.

Project description:In the mol-ecule of the title compound, C(12)H(15)N(3)O(2), the pyrazole ring is oriented at a dihedral angle of 49.64?(6)° with respect to the benzene ring.

3,5-Bis[1-acetyl-5-(4-chloro-phen-yl)-4,5-dihydro-1H-pyrazol-3-yl]-2,6-dimethyl-pyridine.

Project description:The title compound, C(29)H(27)Cl(2)N(5)O(2), contains a central pyridine ring and two functionalized pyrazoline rings. The pyridine ring and the two attached pyrazoline rings are nearly coplanar, whereas the terminal chloro-phenyl rings are nearly perpendicular to the attached pyrazoline rings [dihedral angles = 86.78?(1) and 77.70?(1)°]. Mol-ecules are linked by weak inter-molecular C-H?O hydrogen bonding.

1,2-Bis[(3,5-diphenyl-1H-pyrazol-1-yl)meth-yl]benzene.

Project description:The title compound, C(38)H(30)N(4), a potentially mono- and bidentate ligand, does not seem to form palladium complexes similar to other poly(pyrazol-1-ylmeth-yl)benzenes due to the large steric size of the phenyl substituents on the pyrazole rings. The pyrazole rings have a 21.09?(5)° angle between their mean planes and exhibit a trans-like geometry in which the in-plane lone pairs of electrons on the 2-N nitrogen atoms point in opposite directions.

Amino-(5-{2-[amino-(iminio)meth-yl]hydrazin-1-yl}-3,5-dimethyl-4,5-dihydro-1H-pyrazol-1-yl)methaniminium dinitrate.

Project description:The reaction of aqueous solutions of amino-guanidine hydrogennitrate and acetyl-acetone produces the title pyrazole salt, C(7)H(18)N(8) (2+)·2NO(3) (-). The crystal structure is stabilized by a complex N-H?O hydrogen-bonding network. The difference in the engagement of the two nitrate anions in hydrogen bonding is reflected in the variation of the corresponding N-O bond lengths.

Synthesis and Characterization of Novel 2-(1,2,3-Triazol-4-yl)-4,5-dihydro-1H-pyrazol-1-yl)thiazoles and 2-(4,5-Dihydro-1H-pyrazol-1-yl)-4-(1H-1,2,3-triazol-4-yl)thiazoles

Project description:Reactions of 1-(5-methyl)-1H-1,2,3-triazol-4-yl)ethan-1-ones and benzaldehydes in ethanol under basic conditions gave the corresponding chalcones. Reactions of the chalcones combined with thiosemicarbazide in dry ethanol containing sodium hydroxide afforded the corresponding pyrazolin-N-thioamides. Reactions of the synthesized pyrazolin-N-thioamides and several ketones (namely, ethyl 2-chloro-3-oxobutanoate, 2-bromoacetylbenzofuran, and hydrazonoyl chloride) gave the corresponding novel 2-(1,2,3-triazol-4-yl)-4,5-dihydro-1H-pyrazol-1-yl)thiazoles in high yields (77–90%). Additionally, 2-(4,5-dihydro-1H-pyrazol-1-yl)-4-(1H-1,2,3-triazol-4-yl)thiazoles were obtained in high yields (84–87%) from reactions with N-pyrazoline-thioamides and 4-bromoacetyl-1,2,3-triazoles under basic conditions. The structures of six of the newly synthesized heterocycles were confirmed by X-ray crystallography.
