Abstract
Methods for the preparation of 2-aminobenzophenone and its derivatives published from 1945 through 1979 are reviewed. The various synthetic schemes developed to date for 2-aminobenzophenones allow most derivatives to be prepared readily and in good yield. The review is completed by tables of mono- and di-substituted 2-aminobenzophenones. 1. Introduction 2. Syntheses from 2-Benzoylbenzoic Acids 3. Syntheses from 3-Arylindoles 4.
