N-(4-Chloro-phenyl-sulfon-yl)-2-methyl-propanamide.

ABSTRACT: In the crystal structure of the title compound, C(10)H(12)ClNO(3)S, the N-C bond in the C-SO(2)-NH-C segment has a gauche torsion with respect to the S=O bonds. The mol-ecule is twisted at the S atom with a C-S-N-C torsion angle of -62.3?(3)°. The benzene ring and the SO(2)-NH-CO-C segment form a dihedral angle of 89.3?(1)°. In the crystal, mol-ecules are linked by pairs of N-H?O hydrogen bonds into inversion dimers.

N-(4-Chloro-phenyl-sulfon-yl)-2,2,2-tri-methyl-acetamide.

Project description:In the crystal structure of the title compound (N4CPSTMAA), C(11)H(14)ClNO(3)S, the conformations of the N-H and C=O bonds in the amide group are anti to each other, similar to those observed in N-phenyl-sulfonyl-2,2,2-trimethyl-acetamide (NPSTMAA) and 2,2,2-trimethyl-N-(4-methyl-phenyl-sulfon-yl)acetamide (N4MPSTMAA). The bond parameters in N4CPSTMAA are similar to those in NPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethyl-acetamides and 4-chloro-benzene-sulfonamide. The -SNHCOC- unit including the amide group is essentially planar and makes a dihedral angle of 82.2?(1)° with the benzene ring, comparable to the values of 79.1?(1) and 71.2?(1)° in NPSTMAA and N4MPSTMAA, respectively. The mol-ecules in N4CPSTMAA are linked into a chain by inter-molecular N-H?O hydrogen bonds.

3-(4-Chloro-phenyl-sulfon-yl)-2-methyl-naphtho[1,2-b]furan.

Project description:The title compound, C(19)H(13)ClO(3)S, was prepared by the oxidation of 3-(4-chloro-phenyl-sulfan-yl)-2-methyl-naphtho[1,2-b]furan with 3-chloro-peroxy-benzoic acid. The 4-chloro-phenyl ring makes a dihedral angle of 68.59?(5)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by ?-? inter-actions between the benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.635?(3)?Å], and by C-H?? inter-actions between a methyl H atom and the furan ring of an adjacent mol-ecule. In addition, the crystal structure exhibits inter-molecular C-H?O inter-actions.
