Herein, the novel approach for controlled synthesis of nitrogen doped MnOx (denoted as N-MnO2, N-Mn5O8 and N-Mn3O4) by adjusting the heteroatom nitrogen amount is reported. It was shown that N-MnO2 catalyst is a sustainable and cost-effective heterogeneous catalyst for condensation of 2-aminophenols and o-phenylenediamine with alcs. to afford the corresponding benzoxazoles and benzimidazole, resp. The N-MnO2 catalyst displayed >99.9% yield for benzoxazole synthesis under room temperature and no decay (10 cycles), compared with the negligible activity (∼0%) for MnO2 catalysts. X-ray absorption spectroscopies and exptl. studies uncovered that oxygen vacancies, generated by heteroatom N doping, act as the key role for promoting intramol. oxidative dehydrogenation of alc. and 2-aminophenol derivatives to directly yield desired products. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9Related Products of 99586-31-9).
2-(3-Bromophenyl)benzo[d]oxazole (cas: 99586-31-9) belongs to benzoxazole derivatives. Benzoxazole derivatives have different biological activities. Benzoxazoles are prominent in medicinal chemistry due to their wide spectrum of pharmacological activities such as antiparkinson, inhibition of hepatitis C virus, 5-HT3 antagonistic effect.Related Products of 99586-31-9
