2,2-Dimethyl-N-(2-methyl-phenyl-sulfon-yl)acetamide.

Project description:The asymmetric unit of the title compound, C(11)H(15)NO(3)S, contains two independent mol-ecules in which the amide bonds show a trans conformation. The C-S-N-C torsion angles are -67.4 (2) and 63.8 (2)° in the two independent mol-ecules. In one of the mol-ecules, a methyl group is disordered over two sets of sites with a site-occupation factor of 0.661 (16) for the major occupany component. In the crystal, mol-ecules are packed into chains running along [101] through N-H⋯O(S) hydrogen bonds.

Project description:The conformation of the N-H and C=O bonds in the title compound, C(8)H(7)Cl(2)NO(3)S, is trans. The benzene ring and the SO(2)-NH-CO-C group form a dihedral angle of 79.75 (8)°. Mol-ecules are connected via N-H⋯O hydrogen bonds to form linear supra-molecular chains.

2,2-Dichloro-N-(3,4-dimethyl-phen-yl)acetamide.

Project description:In the title compound, C(10)H(11)Cl(2)NO, the N-H bond is syn to the 3-methyl substituent in the aromatic ring, similar to that observed in N-(3,4-dimethyl-phen-yl)acetamide and to the 3-chloro substituent in 2,2-dichloro-N-(3,4-dichloro-phen-yl)acetamide, and contrasting with the anti conformation observed for the 3-methyl substituent in 2,2,2-trichloro-N-(3,4-dimethyl-phen-yl)acetamide. On the other hand, it is anti to the C=O bond. An inter-molecular N-H⋯O hydrogen bond links mol-ecules into infinite chains along the b axis.

N-(2,4-Dimethyl-phen-yl)-2,2-diphenyl-acetamide.

Project description:The asymmetric unit of the title compound, C(22)H(21)NO, consists of two crystallographically independent mol-ecules (A and B). Each mol-ecule contains two benzene rings and one dimethyl-benzene ring. The dihedral angle between the two benzene rings is 87.75 (16)° in mol-ecule A and 89.25 (16)° in mol-ecule B. In mol-ecule A, the dimethyl-benzene ring forms dihedral angles of 89.65 (8) and 42.98 (11)° with the two benzene rings, whereas the corresponding angles are equal to 63.15 (7) and 58.67 (10)° in mol-ecule B. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif in each mol-ecule. In the crystal, mol-ecules are linked by bifurcated (N,C)-H⋯O hydrogen bonds, generating R(2) (1)(6) ring motifs and forming infinite chains along the a axis. The crystal is further stabilized by C-H⋯π and π-π inter-actions with centroid-centroid distances of 3.8543 (18) and 3.930 (2) Å.

2,2-Dichloro-N-(2,3-dimethyl-phen-yl)acetamide.

Project description:The conformation of the N-H bond in the title compound, C(10)H(11)Cl(2)NO, 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-dichloro-phen-yl)acetamide and the 2-methyl substituent in 2,2-dichloro-N-(2-methyl-phen-yl)acetamide, but in contrast to the anti conformation observed with respect to the 3-methyl substituent in 2,2-dichloro-N-(3-methyl-phen-yl)acetamide. The bond parameters in the title compound are similar to those in 2,2-dichloro-N-phenyl-acetamide and other acetanilides. The mol-ecules of the title compound are linked into chains through N-H⋯O and C-H⋯O hydrogen bonding.

2,2-Dichloro-N-(4-chloro-phenyl-sulfon-yl)-acetamide.

Project description:In the crystal structure of the title compound (N4CPSDCAA), C(8)H(6)Cl(3)NO(3)S, the conformations of the N-H and C=O bonds in the SO(2)-NH-CO-C group are trans to each other, similar to those observed in 2,2-dichloro-N-(phenyl-sulfon-yl)-acetamide (NPSDCAA), 2,2-dichloro-N-(4-methyl-phenyl-sulfon-yl)acetamide (N4MPSDCAA) and N-(4-chloro-phenyl-sulfon-yl)-2,2,2-trimethyl-acetamide (N4CPSTMAA), with similar bond parameters. The -SNHCOC- unit in N4CPSDCAA is essentially planar and makes a dihedral angle of 79.67 (5)° with the benzene ring, comparable to 79.75 (8)° in NPSDCAA, 81.02 (5)° in N4MPSDCAA and 82.2 (1)° in N4CPSTMAA. The mol-ecules in N4CPSDCAA are linked into layers parallel to the (001) plane by inter-molecular N-H⋯O hydrogen bonds.

N-[(3-Ethyl-phen-yl)carbamo-thio-yl]-2,2-di-phenyl-acetamide.

Project description:In the title mol-ecule, C23H22N2OS, the di-phenyl-acetyl and ethyl-benzene groups adopt a trans-cis conformation, respectively, with respect to the S atom across the (S=)C-N bonds. This conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond and a weak C-H⋯S hydrogen bond. The ethyl-substituted benzene ring forms dihedral angles of 87.53 (15) and 73.94 (15)° with the phenyl rings. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into chains along [100]. A weak C-H⋯π inter-action is also observed.

Project description:In the title compound, C(14)H(15)N(3)OS, the phenyl ring is almost perpendicular to the dimethyl-pyrimidine group, with a dihedral angle of 88.1 (3)°. The Csp(2)-S bond of 1.759 (3) Å is significantly shorter than the Csp(3)-S bond of 1.795 (3) Å due to the p-π conjugation.
