Thermolysis of brown coal in the presence of alkali metal hydroxides

Autor: M. I. Chernyshova, Yu. V. Tamarkina, G. F. Raenko, V. A. Kucherenko

Publikováno v: Solid Fuel Chemistry. 51:147-154

The thermolysis (≤500°C) of brown coal impregnated with alkali metal hydroxides MOH was studied. Alkalis cause the cleavage of a three-dimensional coal framework into fragments similar to humic acids. The initial rate of the process increases with

Onium salts QZ (Z = Cl, Br) having a lipophilic (Q = R3NR', where R' = C16H33) or readily extractable (into organic phase) cation (Q = Ph4P) exhibit a high catalytic activity in phase-transfer alkaline hydrolysis of N-benzyloxycarbonylglycine 4-nitro

Heterocyclization of 2-allylthiobenzimidazoles into derivatives of benzimidazo[2,1-b]-1,3-thiazines

Autor: O. P. Shvaika, Nikolai I. Korotkikh, G. F. Raenko

Publikováno v: Chemistry of Heterocyclic Compounds. 31:359-363

It was found that bromination of 2-allylthiobenzimiduzoles in organic solvents forms products of addition of bromine to the olefin bond-2, 3-dibromopropylthiobenzimidazoles, which spontaneously or on heating cyclize into 3-bromobenzimidazo[2,1-b]-1,
