Reductive sulfur extrusion reaction of 2,1,3-benzothiadiazole compounds: A new methodology using NaBH4/CoCl2·6H 2O(cat) as the reducing system

A new simple and efficient methodology for reductive sulfur extrusion from 2,1,3-benzothiadiazole compounds has been developed using NaBH4 in the presence of catalytic amounts of CoCl2·6H2O (1 mol %). This method is an efficient alternative for the generation of various 1,4-disubstituted-2,3-diaminobenzene derivatives from 4,7-disubstituted-2,1,3- benzothiadiazoles. The diamines can be easily converted into 4,7-disubstituted-quinoxaline compounds by simple reaction with glyoxal-sodium bisulfite.

Two-dimensional metal organic complex containing thiazole functional groups, and preparation method and application thereof

The invention discloses a two-dimensional metal organic complex containing thiazole functional groups, and a preparation method and application thereof. According to a technical scheme in the invention, the preparation method comprises the following steps: adding Pb(NO), 4,4'-(benzothiazolyl-4,7-disubstituted)-dibenzoic acid and a solvent, namely N,N-dimethylformamide into a container, and carrying out stirring for 30 minutes at normal temperature until the materials are uniformly mixed; sealing the container, putting the container into an oven, and keeping the container at a temperatureof 368 K for 1 day; carrying out slow cooling to room temperature to obtain a yellow transparent rod-like crystal; and washing the yellow transparent rod-like crystal with N,N-dimethylformamide, andcarrying out filtering and drying to obtain a target product (Pb-btdb). The prepared two-dimensional metal organic complex containing the thiazole functional groups is used as a catalyst and can efficiently catalyze cycloaddition conversion of carbon dioxide and epoxide to prepare cyclic carbonate.
