Abstract
Hydrobromides of [(alkylpyrrol-2(1H)-ylidenio)methyl]pyrroles (alpha,alpha- dipyrrolylmethenes) and of their alpha,beta and beta,beta isomers were prep ared, and their resistance to oxidative thermal degradation was studied. Th e solvation properties of these compounds in various organic solvents were examined spectrophotometrically and calorimetrically.
