STUDIES ON BIPYRIDINIUM SALTS AND THEIR POLYMERS Ⅰ. SYNTHESIS OF 4, 4'-(1, 4-PHENYLENE-)BIS-[N-ALKYL (ARYL)-2, 6-DIPHENYL-] PYRIDINIUM SALTS AND THEIR POLYMERS FROM CORRESPONDING BIPYRYLIUM SALT*

The reaction of pyrylium salt with primary amine has been utilized to synthesize 4,4'-bipyri-dinium salts and pyridinium polymers. Seven new 4,4'-(1,4-phenylene-) bis-[N-alkyl(aryl)-2,6-diphenyl-] pyridinium perchlorates 4 and five corresponding bipyridinium polymers 5 were preparedwith good yields from 4,4'-(1,4-phenylene-) bis-(2,6-diphenyl-) pyrylium perchlorate 3. Preliminarytests have been made for their redox behavior and catalytic activity.
