I found the field of Chemistry very interesting. Saw the article A simple and metal-free one-pot synthesis of 2-substituted-1H-4-carboxamide benzimidazole using 3,6-di(pyridin-2-yl)-1,2,4,5-tetrazine(PYTZ) as catalyst published in 2019.0. Computed Properties of C6H5NO, Reprint Addresses Sun, YQ (corresponding author), Yancheng Teachers Univ, Yancheng, Peoples R China.; Sun, YQ (corresponding author), Yancheng Tongda Pharmaceut Co Ltd, Yancheng, Peoples R China.; Sun, YQ (corresponding author), Jiangsu Marine Ind Res Inst, Yancheng, Peoples R China.; Sun, YQ (corresponding author), Jiangsu Tuoqiu Agrichem Co Ltd, Yancheng, Peoples R China.. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde
In this work, a simple and green method for the convenient synthetic protocol of 2-substituted-1H-4-carboxamide benzimidazole was reported from 2,3-diaminobenzamide and a variety of aldehydes by condensation. The results showed that 2,3-diaminobenzamide and aldehydes could react under visible light irradiation at ambient temperature in the presence of PYTZ and pumping air (or other oxidant) to obtain the desired compound with simple workup. The structures of 20 synthesized compounds were determined by NMR, IR and HRMS (new compound) techniques. The method was efficient, metal free, green, and selective.
Computed Properties of C6H5NO. Bye, fridends, I hope you can learn more about C6H5NO, If you have any questions, you can browse other blog as well. See you lster.
