WebAccording to the preparation method, a 2,4,-6-tris(p-tert-butyl oxyphenoxy) pyrimidine product is synthesized by taking 4,6-dichloro-methylsulfonyl pyrimidine and p-tert-butylphenol as raw materials, wherein the reaction temperature of a reaction system is 10 to 40 DEG C; the reaction time is 10 to 60 minutes. Pyrimidine is an aromatic, heterocyclic, organic compound similar to pyridine (C5H5N). One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has nitrogen atoms at positions 1 and 3 in the ring. The other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) … See more The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives, including the nucleotides cytosine, thymine and uracil, thiamine (vitamin B1) and alloxan. It is also found in … See more The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. For example, 2-hydroxypyrimidine is more properly named 2 … See more As is often the case with parent heterocyclic ring systems, the synthesis of pyrimidine is not that common and is usually performed … See more Because of the decreased basicity compared to pyridine, electrophilic substitution of pyrimidine is less facile. Protonation See more Physical properties are shown in the data box. A more extensive discussion, including spectra, can be found in Brown et al. See more Per the classification by Albert six-membered heterocycles can be described as π-deficient.
