  Cobalt(II) and zinc(II) compounds with unsaturated ligands derived from 2-aminobenzothiazole

  摘要：

  Four zinc(II) (6, 8, 10 and 12) and four cobalt(II) (5, 7, 9 and 11) compounds derived from N-(benzothiazol-2-yl)-dithiocarbamic methyl ester (1) (5 and 6), 1-benzothiazol-2-ylid-3-methyl-thiourea (2) (7 and 8), 1-benzothiazol-2-yl-2,3-dimethyl-iso thiourea (3) (9 and 10) and N-(benzothiazol-2-yl)-S,S'-dimethyl-dithio-carboimine (4) (11 and 12) are reported. The complexes were characterized in the solid state by UV-Vis-NIR diffuse reflectance, IR, mass spectrometry and compounds 5, 9-12 by X-ray single crystal diffraction analyses. In all cases two ligand molecules are bonded to a tetracoordinated metal atom. In compounds 5-10 the ligand is anionic and bidentate with the metal atom in the center of spirocyclic structures formed by two planar unsaturated six membered rings. In compounds 7-10 the metal atom is linked to four nitrogen atoms and in 5 and 6 to two sulfur and two nitrogen atoms. In compounds 11 and 12 the ligand is neutral and monodentate and the metal ion remains coordinated to the chlorine atoms. (C) 2004 Elsevier Ltd. All rights reserved.

  Reactions between CS2 and the exocyclic amino groups of 2-aminobenzothiazoles gave series of molecules bearing thiourea, isothiourea, dithiocarbamate, dithiocarboimine, dimethyldithiocarbamate, methyldithiocarbamate, S-CH3 and O-alkyl thiocarbamic ester, and guanidine groups. Preferred tautomers and conformers were determined. Most compounds present coordinative bonds between the endocyclic sulfur

• A Synthetic Method to Access Symmetric and Non-Symmetric 2-(N,N'-disubstituted)guanidinebenzothiazoles

  日期：——

  Symmetric and non-symmetric 2-(N-H, N-methyl, N-ethylenyl and N-aryl)guanidinebenzothiazoles were synthesized from the reaction of ammonia, methylamine, pyrrolidine and aniline with dimethyl benzo[d]thiazol-2-yl-carbono-dithioimidate (5) as intermediate. The products were characterized by 1H-, 13C-NMR spectroscopy and three of them by X-ray diffraction analysis. HN-phenyl protons formed intramolecular hydrogen bonds that assist the stereochemistry of the second substituent, whereas the HN-alkyl protons were involved in intermolecular hydrogen bonding.
