Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. 72235-52-0, Name is (2,4-Difluorophenyl)methanamine, molecular formurla is C7H7F2N. In a document, author is Dal Magro, J, introducing its new discovery. Synthetic Route of 72235-52-0.
The kinetics of the nitrosation of 2-hydroxyethylpiperidine have been studied in acidic (0.05-0.30 mol dm(-3) HClO4) aqueous media. The reaction rate is first order with respect to nitrite and amine and independent of acidity and shows an experimental isotope effect of 1.73. The most plausible mechanism involves the fast formation of an alkyl nitrite in the protonated amine (equilibrium constant estimated as 0.014 dm(3) mol(-1)). The loss of a proton from this intermediate is the rate-limiting step, and it is followed by a fast internal nitroso group transfer from the oxygen to the nitrogen atom to give the corresponding N-nitroso compound. A comparison of this nitrosation pathway of secondary amines in acid media with the nitrosation of thiomorpholine and piperidine, and with that of amines by alkyl nitrites in basic media is also discussed.
