Hydroquinone combined with FeCl 3 can reduce the methanolysis time of N ‐vinylcarbazole in CH 3 OH from 9 h to 1 h, but the addition of hydroquinone to Fe(NO 3 ) 3 will slow the methanolysis and quench the cyclobutanation process. The addition of H 2 O 2 successfully made the FeCl 3 catalytic cyclobutanization of N ‐vinylcarbazole in the yield from zero up to 33%. Copyright © 2011 John Wiley & Sons, Ltd.
