Anchan, Kavitha; Puttappa, Nagaswarupa H.; Poongavanam, Baburajan; Sarkar, Sujit Kumar published an article in 2021. The article was titled 《Microwave assisted rapid synthesis of phenoxazines and benzopyridoxazines》, and you may find the article in Synthetic Communications.Safety of Methyl 4-fluoro-3-nitrobenzoate The information in the text is summarized as follows:
A facile protocol for the synthesis of phenoxazines and benzopyridoxazines by Smiles rearrangement have been demonstrated in short reaction time under microwave irradiation The control experiments suggest that a reaction proceeds through Smiles rearrangement followed SNAr ring closure by in situ cascade process. In present work, both the electron donating and electron withdrawing groups were tolerant and provided a corresponding phenoxazine/benzopyridoxazine in good to moderate yields. After reading the article, we found that the author used Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Safety of Methyl 4-fluoro-3-nitrobenzoate)
Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9) belongs to methyl benzoate. Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.Safety of Methyl 4-fluoro-3-nitrobenzoate
