Abstract  

3,3′,4,4′-tetramethyl-5,5′-dicarboethoxydipyrrolylmethane-2,2′ and its α,β and β,β′ isomers were synthesized. The compounds were characterized by recording of their proton NMR spectra. The thermal oxidative destruction of the compounds was studied by thermogravimetry. The thermal stability of dipyrrolylmethanes was found to be primarily characterised by molecular isomerism for symmetrically substituted α,α′-and β,β′-dipyrrolylmethanes compared with α,β isomer.
