The title compound, C(14)H(21)NO(2)S, synthesized by N-methyl-ation of cyclo-hexyl-amine sulfonamide with ethyl iodide is of inter-est as a precursor to biologically active sulfur-containing heterocyclic compounds. There are two independent mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the phenyl ring and the cyclo-hexyl ring are 40.29 (11) and 37.91 (13)° in...

In the title compound, C(19)H(16)O(2)S, the sulfur-bound phenyl group is approximately parallel to one of the two phenyl rings of the benzhydryl group, making a dihedral angle of 12.53 (10)°, and forms a dihedral angle of 41.25 (9)° with the other phenyl ring. In the crystal, weak C-H⋯O inter-actions form a two-dimensional network propagating along the bc plane.

Corrosive Sulfur in transformer oil has been the cause of high profile transformer failures in recent years. Oil treatments consisting of copper passivators have been only partially effective. DSI has discovered a multi-step method that has been proven to change oils with corrosive sulfur into non-corrosive status, as well as significantly slowing oxidation and ageing of insulating oil and pape...

The title compound, C(15)H(23)NO(2)S, synthesized by N-methyl-ation of cyclo-hexyl-amine sulfonamide with propyl iodide, is of inter-est as a precursor to biologically active sulfur-containing heterocyclic compounds. The cyclo-hexyl ring exists in the chair form and the dihedral angle between the ring plane of the benzene ring and that of the cyclo-hexyl ring is 50.13 (9)°.

Garlicnin A (1), a new stable, sulfur-containing compound isolated from a fraction of the acetone extracts of Allium sativum L. garlic bulbs, showed the potential to suppress tumor cell proliferation by inhibiting the polarization of M2 alternatively activated macrophages, and its structure was characterized as 3,4-dimethyl-5-(4,5-dithia-1E,7-octadiene)-tetrahydrothiophene-2-sulfoxide-S-oxide, ...

Selenium-73 is a positron emitting non-standard radionuclide, which is suitable for positron emission tomography. A copper-catalyzed reaction allowed no-carrier-added labeling of the anti-inflammatory seleno-organic compound Ebselen with (73) Se and (75) Se under addition of sulfur carrier in a one-step reaction. The new authentically labeled radioselenium molecule is thus available for preclin...

In the title compound, C(23)H(26)N(2)O(2)S, the sulfur-bound phenyl group is aligned approximately parallel to one of the two rings of the benzhydryl group, making a dihedral angle of 1.15 (9)°. The other forms a dihedral angle of 59.20 (9)° with the phenyl group bound to the S atom. In the crystal, mol-ecules are linked into strands along [100] by weak C-H⋯O contacts. Weak C-H⋯π inter-actions ...

The title compound, C(9)H(10)N(2)S, was synthesized according to Gewald procedures by the reaction of cyclo-hexa-none with malonitrile and sulfur in the presence morpholine. The cyclo-hexane ring adopts a half-chair conformation and the thio-phene ring is essentially planar (r.m.s. deviation = 0.05 Å). The crystal packing is stabilized by two inter-molecular N-H⋯N hydrogen bonds, which link the...

The title compound, C(8)H(9)NO(4)S, is of inter-est as a precursor to biologically active sulfur-containing heterocyclic cmpounds. The crystal structure displays the classical O-H⋯O inter-molecular hydrogen bonding typical for carboxylic acids forming dimers. Symmetry-related dimers are, in turn, linked through head-to-tail pairs of inter-molecular N-H⋯O inter-actions, giving rise to a zigzag c...

In the title compound, C(16)H(12)N(2)S(3), the two benzothia-zole groups are oriented differently with respect to the -CH(2)- groups, one being approximately staggered and one nearly eclipsed. A sulfur-π inter-action of 3.3627 (11) Å is observed between the bridging thio-ether S atom and a thia-zole ring. The crystal packing is further stabilized by inter-molecular C-H⋯N and C-H⋯π inter-actions.
