| Abstract: | Mechanisms explaining the formation of pyrroles obtained by UV irradiation of thiophen, the two methylthiophens, the four dimethylthiophens, 2-phenylthiophen, furan, the two methylfurans, and 2,4- and 2,5-dimethylfuran in the presence of n-propylamine are discussed. A comparison of the structure of thiocarbonyl and carbonyl intermediates most likely to be formed by UV irradiation of the substrates with the structure of the experimentally obtained pyrroles indicates that the formation of pyrroles from thiophenes and furans seems to follow mechanisms described in Schemes 1 and 4. |
