Abstract

The indolization of deoxybenzoin o, m, p (Me, MeO, Cl), p-NO2 and m-EtO- phenylhydrazones (1) by the above reaction has been examined. All the reactions are carried out at room temperature and high yields of the corresponding indoles (2) are obtained even when-NO2 substituent is present. In this case longer reaction time is necessary. Alkoxyphenylhydrazones give the corresponding indoles (2) in high yields ...
