N-doped porous carbon (NC) was synthesized from sugar cane bagasse, which is a sustainable and widely available biomass waste. The preferred NC sample had a well-developed porous structure, a graphene-like surface morphology and different N species. More

A metal-free heterogeneous photocatalysis has been developed for the synthesis of benzothiazoles via intramolecular C-H functionalization/C-S bond formation of thiobenzanilides by inexpensive graphitic carbon nitride (g-C3N4) under visible-light irradiation. This reaction provides access to a broad range of 2-substituted benzothiazoles in high yields under an air atmosphere at room temperature without addition of a strong base or organic oxidizing reagents. In addition, the catalyst was found to be stable and reusable after five reaction cycles.

Paragraph 0027-0029, (2021/06/22)
The invention discloses a method for preparing an alkyl benzothiazole derivative under visible light, which specifically comprises the following steps: under the protection of inert gas, adding N-(2-bromophenyl) alkyl thioamide and inorganic base into a reaction container provided with a stirring device, then adding dimethyl sulfoxide, stirring and reacting for 24 hours at room temperature under the irradiation of visible light, and obtaining the alkyl benzothiazole derivative. Under the condition of not adding any photosensitizer or transition metal catalyst, sodium phosphate is used as alkali, and under the irradiation of a 45W household compact fluorescent lamp, a series of intramolecular cross-coupling reactions of N-(2-bromophenyl) alkyl thioamide are realized. In addition, the alkylbenzothiazole derivative can be obtained with high yield. The whole process is green, efficient and easy to operate, and the method is a good method for synthesizing the alkylbenzothiazole derivative.
