Benzothiazole derivatives as inhibitors of corrosion of steel St3 in hydrochloric acid

Benzothiazole derivatives as inhibitors of corrosion of steel St3 in hydrochloric acid. Makovei, G. L.; Ushakov, V. G.; Aleinik, R. L.; Pushkareva, V. V.; Koroleva, V. R.; Tolmachev, A. A. (Kiev. Politekh. Inst., Kiev, USSR). Zashch. Met., 23(1), 142-7 (Russian) 1987. CODEN: ZAMEA9. ISSN: 0044-1856. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 71 As part of an on-going study, the inhibiting effects on steel St3 in HCl of 2-aminobenzothiazole (I) [136-95-8], 2-methylbenzothiazole (II) [120-75-2], and 2-methyl-5-aminobenzothiazole (III) [13382-43-9], as well as the effect on the protective properties of I of g-rays from 60Co in the absorbed dose range up to 10 MGy were studied. Tests were made to relate the mechanism of H evolution and anodic ionization of Fe to the distribution of p-electron d. on reaction centers of the mols. The following characteristics of the inhibiting action of the above compds. were studied: corrosion rate, protective effect, polarization resistance, characteristics of cathodic H evolution and anodic Fe ionization, and the effective activation energy of the corrosion process.

Synthesis and molecular structure of heterocyclic Troger's bases derived from C-amino heterocycles. Cudero, Jose; Pardo, Carmen; Ramos, Mar; Gutierrez-Puebla, Enrique; Monge, Angeles; Elguero, Jose (Dept. de Quimica Organica I, Univ. Complutense, Madrid E-28040, Spain). Tetrahedron, 53(6), 2233-2240 (English) 1997 Elsevier. CODEN: TETRAB. ISSN: 0040-4020. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Fourteen amino heterocycles were allowed to react under different exptl. conditions for formation of Troger's bases. Aminoazoles and -benzazoles yielded the corresponding Troger's bases while aminoazines and -benzazines failed to react. The exception was 6-aminoquinoline which yielded the corresponding Troger's base. When there are two positions of cyclization, the reaction is always regioselective.
