The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 3,5-Dimethyl-4-nitropyridine 1-oxide(SMILESS: O=[N+](C1=C(C)C=[N+]([O-])C=C1C)[O-],cas:14248-66-9) is researched.Application In Synthesis of 2,3-Dibromo-1-propanol. The article 《Photosensitized reduction of 4-nitropyridine N-oxides》 in relation to this compound, is published in Bulletin of the Chemical Society of Japan. Let’s take a look at the latest research on this compound (cas:14248-66-9).
Irradiation of EtOH or Me2CHOH solutions of nitropyridine oxides (I; R = H, Me; R1 = NO2) in the presence of MeCOCOMe gave the corresponding I (R1 = NHOH), indicating H abstraction from a solvent mol. by the lowest π, π* triplet state of the nitro compound
After consulting a lot of data, we found that this compound(14248-66-9)Synthetic Route of C7H8N2O3 can be used in many types of reactions. And in most cases, this compound has more advantages.
