Reactivity of Pyrrole Pigments. Part VII Autoxidation of Model Compounds for 5(2H)-Dipyrrylmethanones and 3,4-Dihydro-5(1H)-Pyrromethenones

Article abstract of DOI:10.1007/BF00809439

The autoxidation in alkine media and in the dark of some 5-methyl substituted 3,4-dimethyl-3-pyrrolin-2-ones and 5-methylene substituted pyrrolin-2-ones is studied.Both types of compounds are found to give autoxidation products that indicate very characteristic reaction pathways. - Keywords: Autoxidation; Bile pigments; Dihydropyrromethenoes; Dipyrrylmethanones
