Preparation of 2-azinylthio-3-carboxypyridines as herbicides: Preparation of 2-azinylthio-3-carboxypyridines as herbicides. Heinemann, Ulrich; Santel, Hans Joachim; Luerssen, Klaus; Schmidt, Robert R. (Bayer A.-G., Germany). Ger. Offen. DE 4022478 A1 16 Jan 1992, 12 pp. (Germany). CODEN: GWXXBX. CLASS: ICM: C07D401-12. ICS: C07D213-70; A01N043-54; A01N043-66.

APPLICATION: DE 90-4022478 14 Jul 1990. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 5 Title compds. [I; R1 = H, alkyl, alkali metal, (substituted) ammonium; R2 = H, halo, alkyl, alkoxy, haloalkyl; R3, R4 = H, alkyl, alkoxy, alkylthio, haloalkyl, haloalkoxy, haloalkylthio; X = N, CR5; Z = N, CR6; R5 = H, cyano; R6 = H, alkyl], were prepd. as herbicides (no data). Thus, a mixt. 38521-46-9 and 113583-35-0 which are cas registry numbers of substances are two of reagents here. of 2-mercaptonicotinic acid, 4,6-dimethoxy-2-methylsulfonylpyrimidine, K2CO3, and DMF were heated 18 h at 60° to give 33% title compd. II. I are said to show superior pre- and postemergent herbicidal activity. .

Crystal structure and spectral characterization of dimethylthallium(III) complexes with 2-mercaptonicotinic acid and esters: Crystal structure and spectral characterization of dimethylthallium(III) complexes with 2-mercaptonicotinic acid and esters. Toma, Monica; Sanchez, Agustin; Garcia-Tasende, Maria S.; Casas, Jose S.; Sordo, Jose; Castellano, Eduardo E.; Ellena, Javier ( Department of Inorganic Chemistry, "Alexandru Ioan Cuza" University, Iasi RO-700506, Rom.).

DOCUMENT TYPE: Journal; (online computer file) CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 Synthesis, spectral properties and crystal structure of dimethylthallium(III) complexes with 2-mercaptonicotinic acid (2mna), 2-mercapto-methyl-nicotinate (2mmn), 2-mercapto-ethyl-nicotinate (2men) and 2-mercapto-isopropyl-nicotinate (2min) are reported. The compds. were characterized using IR, multinuclear NMR (1H, 13C, 205Tl) and mass spectrometry (electrospray, ES-API). The mol. structures of [TlMe2(2mna)]×H2O, (1), [TlMe2(2mmn)], (2), [TlMe2(2men)], (3) and [TlMe2(2min)], (4) were detd. by the single-crystal x-ray diffraction. In 1, the monodeprotonated O,S-bidentate ligand chelates one dimethylthallium(III) unit and simultaneously bridges (O and S) between two of these organometallic units. The Tl-O1' and Tl-S interactions are leading to polymeric chain linked in a three-dimensional network by the H bonds formed between the H2O mol. and the O O(2) atom of the acid.In this study，38521-46-9 is also used. The Tl atom is in a distorted octahedral environment with a [TlC2O2S2] kernel. Compds. 2-4 are similar, in all the cases already mentioned the ligand is NH deprotonated and is strongly coordinated to two dimethylthallium(III) units through the N and S atoms. Two addnl. weak interactions with the O and S atoms lead to a [TlC2NOS2] kernel for the metal atom, in which the coordination polyhedron is a very distorted octahedron with the Me groups occupying the apical positions. .
