The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Ethyl 3,5-Dimethyl-2-pyrrolecarboxylate( cas:2199-44-2 ) is researched.Category: thiazolidine.Berezin, M. B.; Semeikin, A. S.; Yutanova, S. L.; Antina, E. V.; Guseva, G. B.; V’yugin, A. I. published the article 《Synthesis and properties of (1,2,3,7,9-pentamethyldipyrrolylmethen-8-yl)-(1,2,3,7,8-pentamethyldipyrrolylmethen-9-yl)methane and bis(1,2,3,7,9-pentamethyldipyrrolylmethen-8-yl)trifluoromethylmethane dihydrobromides》 about this compound( cas:2199-44-2 ) in Russian Journal of General Chemistry. Keywords: bisdipyrrolylmethene preparation UVvis thermal oxidative degradation. Let’s learn more about this compound (cas:2199-44-2).
(1,2,3,7,9-Pentamethyldipyrrolylmethen-8-yl)(1,2,3,7,8-pentamethyldipyrrolylmethen-9-yl)-methane and bis(1,2,3,7,9-pentamethyldipyrrolylmethen-8-yl)trifluoromethylmethane hydrobromides were synthesized and characterized spectrally (1H NMR, IR, electron absorption spectra). A comparative study was performed of the effect of the bonding site (α- or β-position of the dipyrrolylmethene) with the methane structural fragment connecting two dipyrrolylmethene chromophores, and trifluoromethyl group on the spectral properties of the mols. of compounds dissolved in organic solvents of different nature and their resistance to thermal oxidative degradation
