Abstract
Reaction of 1 -alkyl and 1 -aryl-5, 6 -benzolepidinium quaternary salts with orthoformic ester in pyridine gives symmetrical 9 -carbocyanine dyes hitherto undescribed in the literature. The effects of substituents at the para position in the N-phenyl ring resemble the effects of the same in the heterocyclic ring, indicating that these substituents are conjugated with the latter. The molecules of the dyes synthesized are shown to exhibit steric hindrance.
