2,2'-Sulfonyl-dipyrazine 4-oxide.

ABSTRACT: In the title compound, C(8)H(6)N(4)O(3)S, the dihedral angle between the pyrazine rings is 85.04?(1)°. In the crystal, mol-ecules are arranged along the a axis and are linked by C-H?N hydrogen bonds and pyrazine-pyrazine ?-? inter-actions [centroid-centroid distance = 3.800?(1)?Å, forming an infinite chain array. The chains are connected by C-H?O(oxide) hydrogen bonds into layers lying parallel to the ab plane. Along the c axis, the layers are stacked and linked through C-H?O(sulfon-yl) inter-actions, forming a three-dimensional network.

In the title compound, C(8)H(6)N(4)O(3)S, the dihedral angle between the pyrazine rings is 85.04 (1)°. In the crystal, mol-ecules are arranged along the a axis and are linked by C-H⋯N hydrogen bonds and pyrazine-pyrazine π-π inter-actions [centroid-centroid distance = 3.800 (1) Å, forming an infinite chain array. The chains are connected by C-H⋯O(oxide) hydrogen bonds into layers lying parallel to the ab plane. Along the c axis, the layers are stacked and linked through C-H⋯O(sulfon-yl) inter-ac ...[more]

2,2-Dichloro-N-(4-methyl-phenyl-sulfonyl)acetamide.

Project description:The N-H and C=O bonds in the title compound, C(9)H(9)Cl(2)NO(3)S, are trans to each other, similar to what is observed in 2,2,2-trimethyl-N-(phenyl-sulfon-yl)acetamide and 2,2,2-trimethyl-N-(4-methyl-phenyl-sulfon-yl)acetamide. The bond parameters in the title compound are also similar to those in the aforementioned two structures. N-H?O hydrogen bonds connect the mol-ecules into chains running along the a axis.

catena-Poly[[(2,2'-bipyridine)-manganese(II)]-?(3)-4,4'-sulfonyl-dibenzoato].

Project description:In the title compound, [Mn(C(14)H(8)O(6)S)(C(10)H(8)N(2))](n), the Mn(II) ion is coordinated by four O atoms from three 4,4'-sulfonyl-dibenzoate (sdba) ligands and two N atoms from one 2,2'-bipyridine (2,2'-bipy) ligand in a distorted octa-hedral geometry. The manganese atoms are alternately bridged either by two sdba ligands, with an Mn?Mn separation of 12.284?(1)?Å, or by two carboxyl-ate groups from two sdba ligands, with an Mn?Mn separation of 4.064?(1)?Å, thus producing polymeric chains propagated in [101]. Weak inter-molecular C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance of 3.730?(3)?Å between the aromatic rings of neighbouring polymeric chains] further stabilize the crystal packing.

Diethyl 2,2'-[(5-dimethyl-amino-1-naphth-yl)sulfonyl-imino]diacetate.

Project description:In the title compound, C(20)H(26)N(2)O(6)S, the N atom of the dimethyl-amino group is displaced by 0.113?(2)?Å from the plane of the naphthalene ring system. The two eth-oxy groups adopt zigzag conformations. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules, forming a three-dimensional network. Both ethyl groups are disordered over two sites with the ratios of refined occupancies being 0.857?(16):0.143?(16) and 0.517?(14):0.483?(14).

2,2'-[Ethane-1,2-diylbis(sulfanedi-yl)]bis-(pyridine N-oxide).

Project description:The tile compound, C(12)H(12)N(2)O(2)S(2), lies on an inversion center. The two pyridyl rings are parallel to each other. The structure is devoid of any classical hydrogen bonds due to lack of appropriate donors and acceptors for such bonds. However, non-classical hydrogen bonds of the types C-H?O and C-H?S stabilize the structure.

2,2'-Bipyridin-1'-ium 1-oxide bromide monohydrate.

Project description:The title compound 2,2'-bipyridin-1'-ium 1-oxide bromide crystallizes as a monohydrate, C10H9N2+·Br-·H2O. Structural disorder is observed due to the fact that protonation, as well as oxidation, of the N atoms of 2,2'-bi-pyridine occurs at either of the N atoms. The disorder extends to the remainder of the cation, with a refined occupancy rate of 0.717?(4) for the major moiety. An intra-molecular N-H?O hydrogen bond forces the bi-pyridine unit into an s-cis conformation. Each pair of neighbouring 2,2'-bipyridin-1'-ium ions forms a dimeric aggregate by hydrogen bonds between their respective N-O and the N-H functions. These dimers and hydrogen-bonding inter-actions with bromide ions and the water mol-ecule give rise to a complex supra-molecular arrangement.

Facile Synthesis of Sulfonyl Chlorides/Bromides from Sulfonyl Hydrazides.

Project description:A simple and rapid method for efficient synthesis of sulfonyl chlorides/bromides from sulfonyl hydrazide with NXS (X = Cl or Br) and late-stage conversion to several other functional groups was described. A variety of nucleophiles could be engaged in this transformation, thus permitting the synthesis of complex sulfonamides and sulfonates. In most cases, these reactions are highly selective, simple, and clean, affording products at excellent yields.
