Specific rates for reactions of N-methyl- and N-ethylquinaldinium iodides containing aryl and alkyl substituents have been compared.For reaction with substituted N,N'-diphenylformamidines attempts at correlation between specific rates and the Hammett's ? constants of substituents at phenyl rings in amidine have been made.An unexpected, negative effect of bases on the reaction rate has been observed.Unreported 21 hemicyanine dyes have been synthesized.
