Green Synthesis: A Novel Method for Bromination of 7-AminoPhthalide
preprintrevised on 10.01.2021, 01:29 and posted on 11.01.2021, 11:45 by Sudershan Reddy Gondi
A novel method for preparing a bromo substituted 7-Amino-phthalides and 7-
Amino-3-hydroxy-phthalides via the bromonium ion intermediate under acidic conditions at
higher temperature were developed. The results will illustrate the potential utility of this
method as an environment-friendly process for synthesis of bromo substituted aryl amines,
along with conservation of half mole equivalent of halides.
