Pyrimidines

1992
This chapter explores pyrimidines. Formal replacement of a CH unit in pyridine by a nitrogen atom leads to the series of three possible diazines: pyridazine, pyrimidine, and pyrazine. Like pyridine, they are fully aromatic heterocycles. The effect of an additional nitrogen atom as compared to pyridine accentuates the essential features of pyridine ...
