Studies on ketene and its derivatives. CXIII. Reaction of dichloroketene with aromatic amine N-oxides was written by Katagiri, Nobuya;Niwa, Ryuji;Furuya, Yoichi;Kato, Tetsuzo. And the article was included in Chemical & Pharmaceutical Bulletin in 1983.SDS of cas: 3718-65-8 This article mentions the following:
Treating pyridine 1-oxide (I) with Cl2C:C:O gave 4 products, pyridines II (R = H, R1 = CHCl2; R = CHCl2, R1 = H; R2 = H) and furopyridines III (R3 = OH, Cl). Reaction of Cl2C:C:O with I, followed by treatment with MeOH, gave II (R = CHCl2, CCl2CO2Me, R1 = H; R = H, R1 = CCl2CO2Me; R2 = H). Similar reaction of Cl2C:C:O with methylpyridine 1-oxides gave the corresponding 2-dichloromethyl- and 4-dichloromethylpyridines. However, reaction of Cl2C:C:O with 2,6-dimethylpyridine 1-oxide, followed by treatment with MeOH gave II (R = CHCl2; R1 = R2 = Me) and bis(pyridyl)dichloromethane IV. Cl2C:C:O reacted with quinoline 1-oxide and isoquinoline 2-oxide to give the corresponding Cl2CH derivatives In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8SDS of cas: 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of â?8.7 à 10â? cm3·molâ?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·molâ? in the liquid phase and 140.4 kJ·molâ? in the gas phase. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.SDS of cas: 3718-65-8
