Several electron attracting groups have been substituted on the nitrogen atom to decrease the electron density of the pyrrole ring in order to make it more suitable for photoaddition reactions. Once it was found that N ‐benzoylpyrrole is the only compound of the series studied, capable of undergoing oxetane formation, other carbonyl compounds in addition to benzophenone were tested as possible addends to the ring. Successful additions were observed when 3‐ and 4‐benzoyl‐pyridine were used.
