Did you know?

SpletYes, the pKa of the conjugate acid of pyridine is about 5.2, and for the deprotonation step, we are comparing this value with the pKa of the conjugate acid of an alcohol or an ether.These are around the negative 2-4 region and the reaction is expected to work since the pKa goes higher (-3 to 5.2).Remember, any acid-base reaction goes towards the …

Splet07. jun. 2024 · Vilsmeier Haack Reaction. ... One of the most common methods of pyridine synthesis is condensation-based reactions. In the more traditional reactions with acid-catalyzed dehydrations in the final steps <2002J(P1)1663, 2002CC1682>, the use of microwave generators has been an advantage. The microwave conditions are simply … SpletCatalyst: SOCl2, pyridine (for synthesis of alkyl chlorides) Catalyst: PBr3, ether, at 35 degC (for synthesis of alkyl bromides) less acidic and less likely to cause acid-catalyzed rearrangements than the HX method.
