Abstract (English):
Studied nitration 3.5-dihydroxy-3-hydroxy-5-bromo derivatives of pyridine. It is shown that nitration of 3-hydroxy-5-bromopyridine sulfur nitrogen and nitric acid-acetic mixtures leads to the formation of the corresponding 2,6-dinitroproizvodnyh. Using an acetic acid-nitric mixture nitrating factor increased activity resulted in the formation of 2,4,6-trinitroproizvodnogo. Thus, the first time we received 2,4,6-trinitro derivatives 3,5-di-substituted pyridine.
