Herein, a novel green method of synthesizing benzothiazolones such as I [R = H, 6-Me, 6-OMe, 6-Cl, 6-Br] via cyclocarbonylation of 2-aminothiophenols with CO2 was developed. A series of organic bases was investigated for the catalysis of cyclocarbonylation, among which 1,5-diazabicyclo[4.3.0]non-5-ene displayed the best catalytic activity. Then, various reaction parameters such as CO2 pressure, temperature, amount of catalyst and reaction time for the catalytic performance were studied. In the experiment, the researchers used many compounds, for example, 6-Chlorobenzo[d]thiazol-2(3H)-one (cas: 62266-81-3Related Products of 62266-81-3).
6-Chlorobenzo[d]thiazol-2(3H)-one (cas: 62266-81-3) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Various laboratory methods exist for the organic synthesis of thiazoles. Prominent is the Hantzsch thiazole synthesis is a reaction between haloketones and thioamides.Related Products of 62266-81-3
