Cruege, Francis published the artcileBasic properties of dimethylamino derivatives of pyridine and pyrimidine, Recommanded Product: N,N-Dimethylpyrimidin-4-amine, the publication is Bulletin de la Societe Chimique de France (1970), 3889-94, database is CAplus.
A correlation exists between the free enthalpy of complexation (with PhOH) and the intrinsic pKa of (dimethylamino)pyridines and -pyrimidines. 2-Dimethylamino isomers are the most basic compounds, and the steric hindrance effect of the 2-dimethylamino group is discussed.
Bulletin de la Societe Chimique de France published new progress about 31401-45-3. 31401-45-3 belongs to pyrimidines, auxiliary class Pyrimidine,Amine, name is N,N-Dimethylpyrimidin-4-amine, and the molecular formula is C6H9N3, Recommanded Product: N,N-Dimethylpyrimidin-4-amine.
