Abstract

The Photoaddition of Pyrroles to Arylethenes and Arylethynes. -Pyrrole and N-methylpyrrole efficiently quenched the fluorescence of the arylethenes and arylethynes. Substituted pyrroles (1:1 and 2:1 adducts) are formed from irradiation of the phenylethenes with pyrrole, and 2-styrylpyrroles result from the phenylethynes. Data for the quenching of the fluorescence are presented. -(AUSTIN, M.; COVELL, C.; GILBERT, A.; HENDRICKX, R.; Liebigs Ann./Recl. (1997) 5, 943-946; Dep. Chem., Univ.
