B. Thimme Gowda,Ingrid Svoboda,Sabine Foro,Shi-qi Dou
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536807064847
Abstract: The conformation of the N—H bond in the structure of the title compound, C9H10ClNO, is syn to the meta-methyl group, in contrast to the anti conformation observed with respect to the meta-nitro group in 2-chloro-N-(3-nitrophenyl)acetamide. The asymmetric unit of the title compound contains two molecules. The geometric parameters of the title compound are similar to those of 2-chloro-N-(4-methylphenyl)acetamide, 2-chloro-N-(3-nitrophenyl)acetamide and other acetanilides. Dual intermolecular N—H...O hydrogen bonds link the molecules in the direction of the a axis.

Abstract: The conformation of the N—H bond in the title compound, C10H11Cl2NO, is syn to both the 2- and 3-methyl substituents in the aromatic ring, similar to that of the 2-chloro and 3-chloro substituents in 2,2-dichloro-N-(2,3-dichlorophenyl)acetamide and the 2-methyl substituent in 2,2-dichloro-N-(2-methylphenyl)acetamide, but in contrast to the anti conformation observed with respect to the 3-methyl substituent in 2,2-dichloro-N-(3-methylphenyl)acetamide. The bond parameters in the title compound are similar to those in 2,2-dichloro-N-phenylacetamide and other acetanilides. The molecules of the title compound are linked into chains through N—H...O and C—H...O hydrogen bonding.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808000408
Abstract: The conformation of the N—H bond in the title compound (23DCPCA), C8H6Cl3NO, is syn to both the 2- and 3-chloro substituents in the aromatic ring, similar to the 2-chloro substituent in 2-chloro-N-(2-chlorophenyl)acetamide (2CPCA), the 2- and 3-chloro substituents in N-(2,3-dichlorophenyl)acetamide (23DCPA) and in 2,2-dichloro-N-(2,3-dichlorophenyl)acetamide (23DCPDCA). The bond parameters in 23DCPCA are similar to those in 2-chloro-N-(phenyl)acetamide, 2CPCA, 23DCPA, 23DCPDCA and other acetanilides. The molecules in 23DCPCA are linked into chains through N—H...O hydrogen bonding.

Abstract: The asymmetric unit of the title compound, C20H24N2O6S2, comprises one half-molecule, the remaining portion being generated via an inversion centre. The dihedral angle between the plane of the benzene ring and the SO2—NH—C(O)—C—C segment is 89.9 (1)°. In the crystal, intermolecular N—H...O(S) hydrogen bonds link the molecules into infinite chains in [101].

Abstract: Medicinal chemistry plays an important role in development of drug for cure; maintain and improved health of human being. It is also equally important to design chemical entities for prevent the growth of micro-organism, which come in contact with human being in day-to-day life. We have synthesized 2-chloro-N-alkyl/aryl Acetamide derivatives with an aim as new bioactive agent, which can be used as anti microbial agents such as herbicides, antifungal, disinfectant. The present study involves the synthesis, purification and characterization of various N-substituted chloroacetamide derivatives. The chloroacetyl chloride treated with various aliphatic and aromatic amines at room temperature with stirring for few hours with monitoring reaction by thin layer chromatography gave 2-chloro-N-alkyl/aryl Acetamide as solid compounds. We checked the melting point of synthesized compounds with an open ended capillary tube method. The spectral techniques like Infra red and GC-MS have been used for characterization and establishment of structure of synthesized compounds. The antimicrobial screening of the synthesized chloroacetamides have shown excellent antibacterial and antifungalactivity.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809011660
Abstract: The N—H bond in the title compound, C8H7Cl2NO, is anti to the meta-chloro substituent in the aromatic ring in both independent molecules comprising the asymmetric unit. The C=O bond is anti to the N—H bond and is also anti to the methylene H atoms. Intermolecular N—H...O hydrogen bonds link the molecules into supramolecular chains.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810003375
Abstract: In the title compound, C15H10Cl3NO2, an intramolecular N—H...O hydrogen bond forms a six-membered ring and enforces an almost coplanar conformation for the acetamido group, the central benzene ring and the bridging carbonyl C—C(=O)—C group: the dihedral angles between the benzene ring and the acetamide and carbonyl C—C(=O)—C planes are 7.06 (11) and 7.17 (12)°, respectively. The dihedral angle between the two benzene rings is 67.43 (9)°. Because a strong hydrogen-bond donor is involved in the intramolecular interaction, the crystal packing is determined by weak C—H...O and C—H...Cl interactions.

Sampath Natarajan,Rita Mathews
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812001638
Abstract: In the title compound, C21H18O2SSe, the dihedral angle between the cis phenyl rings is 64.3 (1)° and those between the toluene and the phenyl rings are 21.1 (2) and 72.0 (1)°, respectively. An intramolecular Se—H...O hydrogen bond occurs. In the crystal, molecules are connected by C—H...O hydrogen bonds and weak C—H...π interactions help to consolidate the crystal packing.
