Abstract
Isolated yield. Asterisk indicates some of the amine hydrochloride present as catalyst. Diketone dissolved in hot (155" C) aniline (10 min). produced via the diketone. New compound. e Refluxing 22.5 h also gave 50% yield. None of the pyrrole could be No attempt made to prepare compound by Paal-Knorr procedure. the carbonyl group. We have found no reports in the literature of the successful reaction of Wittig reagents with the carbonyl ...
