(RS)-1-(1-Acetyl-indolin-5-yl)-2-chloro-propan-1-one.

ABSTRACT: The mol-ecule of the title compound, C(13)H(14)ClNO(2), is roughly planar [maximum deviation = 0.060 (2) Å] with the disordered Cl/CH(3) group asymetrically distributed on both sides of the mean plane. Indeed, the Cl and CH(3) located on the stereogenic carbon exchange each other with occupancy factors in the ratio 0.60:0.40. The whole crystal is a racemate. Non-classical C-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance = 3.6959 (9) Å] between symmetry-related phenyl rings stabilize the crystal structure.

Crystal structure of 6-chloro-5-(2-chloro-eth-yl)-3-(propan-2-yl-idene)indolin-2-one.

Project description:The title compound, C13H13Cl2NO, has a 3-(propan-2-yl-idene)indolin-2-one core with a Cl atom and a chloro-ethyl substituent attached to the aromatic ring. Two atoms of the aromatic ring and the chloro-ethyl substituent atoms are disordered over two sets of sites with a refined occupancy ratio of 0.826 (3):0.174 (3). In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif.

(RS)-1-[5-(2-Chloro-prop-yl)indolin-1-yl]ethanone.

Project description:In the title compound, C(13)H(16)ClNO, the acetyl-indoline moiety is roughly planar (r.m.s. deviation = 0.0048?Å). The chloro-propyl group is out of the plane and is statistically disordered over two positions. Indeed, the Cl and CH(3) groups located on the stereogenic carbon exchange with each other. The whole crystal is a racemate. Non-classical C-H?O hydrogen bonds between symmetry-related benzene rings stabilize the crystal structure.

3,3-Dichloro-1-(chloro-meth-yl)indolin-2-one.

Project description:In the title compound, C(9)H(6)Cl(3)NO, the pyrrole ring is almost coplanar with the benzene ring [dihedral angle = 1.90?(9)°], while the Cl-C-N-C torsion angle is 98.78?(17)°. In the crystal, pairs of mol-ecules are inter-connected by pairs of Cl?Cl inter-actions [3.564?(5)?Å], forming dimers, which are further peripherally connected through inter-molecular C-H?O=C and ?-? inter-actions [centroid-centroid distances = 4.134?(7), 4.134?(6) and 4.238?(7)?Å], forming a two-dimensional network.

Project description:The non-H atoms of the title compound, C(9)H(8)Cl(2)N(2)O, lie nearly on a plane (r.m.s. deviation = 0.110?Å), and the C=N double bond has a Z configuration. In the crystal, adjacent mol-ecules are linked by an N-H?O(carbon-yl) hydrogen bond, forming a chain running along [100].

2,3-Dibromo-1,3-bis-(4-chloro-phen-yl)propan-1-one.

Project description:In the title compound, C(15)H(10)Br(2)Cl(2)O, the terminal benzene rings make a dihedral angle of 31.1?(2)° with each other.

Project description:In the title compound, C(16)H(9)F(4)N(3)O(2), the dihedral angle between the aromatic ring systems is 4.10 (14)° and a bifurcated intra-molecular N-H⋯(O,F) hydrogen bond generates an S(6) ring for the O-atom acceptor and an S(5) ring for the F-atom acceptor. A short C-H⋯O conact also occurs. In the crystal, mol-ecules are linked by C-H⋯O inter-actions.

1-{3-(4-Chloro-phen-yl)-5-[4-(propan-2-yl)phen-yl]-4,5-di-hydro-1H-pyrazol-1-yl}propan-1-one.

Project description:In the title compound, C21H23ClN2O, the dihedral angle between the benzene rings is 83.2?(6)°, while the mean plane of the pyrazole ring [r.m.s. deviation = 0.043?(1)?Å] makes dihedral angles of 3.4?(3) and 86.2?(1)° with the benzene rings. In the crystal, a pair of weak C-H?O inter-actions between the benzene ring and the propan-1-one group link the mol-ecules into an inversion dimer with an R 2 (2)(16) graph-set motif. In addition, a weak ?-? stacking inter-action [centroid-centroid distance = 3.959?(4)?Å] connects the dimers into a tape running along [201].

2-[4-(2-Chloro-acet-yl)phen-yl]-2-methyl-1-(pyrrolidin-1-yl)propan-1-one.

Project description:The asymmetric unit of the title compound, C16H20ClNO2, contains two mol-ecules in which the dihedral angles between the benzene ring and the plane of the amide unit are 77.4 (1) and 81.1 (1)°.
