Synthesis of 3,5-Dibromopyridines with –NH(CH2)mSO3Na (m= 3 and 4) Groups at the 2-Position of Pyridine and Use of the Dibromo Compound for Polymer Synthesis
Synthesis of 3,5-Dibromopyridines with –NH(CH<sub>2</sub>)<i><sub>m</sub></i>SO<sub>3</sub>Na (<i>m</i>= 3 and 4) Groups at the 2-Position of Pyridine and Use of the Dibromo Compound for Polymer Synthesis
Reactions of 2-amino-3,5-dibromopyridine with sultones gave 3,5-dibromopyridines with –NH(CH2)mSO3Na (m = 3 and 4) groups at the 2-position of pyridine. The obtained compound served as a starting material for polypyridine with –NH(CH2)mSO3H side chains.
