Structure Elucidation of a Cryptic Condensation Product from Diacetyl and Arylamine – Then and Now
Some 70 years ago, the reaction of diacetyl (1) and arylamines (2) in hot phosphoric acid was reported to give a new type of condensation products, but no structure was assigned to them. The case is presented to recapitulate the methods and rationales used in classical structure elucidation of organ...
