Abstract
Abstract— 1‐Aryl‐2‐methyl‐4,5‐dihydropyrrol‐3‐carboxylic acid ethyl ester (a cyclic enamine) was observed to dehydrogenate to give 1‐aryl‐2‐methyl‐pyrrol‐3‐carboxylic acid ethyl ester upon irradiation in the presence of oxygen and in the presence or absence of meso‐tetraphenylporphine (TPP). N‐Aryl cyclic amines were shown to be singlet oxygen sensitizers.
