Reaction of 3-(trifluoroacetyl)chromones with ethylenediamine and o-phenylenediamine depending on the nature of substituents and the reaction conditions afforded either mono-adducts, 3-[(2-aminoethyl)aminomethylidene]-and 3-[(2-aminophenyl)aminomethylidene]-2-hydroxy-2-(trifluoromethyl)chroman-4-ones, or bis-adducts, N,N′-ethylenebis-and N,N′-o-phenylenebis[3-aminomethylidene-2-hydroxy-2-(trifluoromethyl)chroman-4-ones].
根据取代基的性质和反应条件的不同,3-(三氟乙酰基)铬酮与乙二胺和邻苯二胺的反应可产生单加成物、3-[(2-氨基乙基)氨基亚甲基]-和 3-[(2-氨基苯基)氨基亚甲基]-2-羟基-2-(三氟甲基)色满-4-酮,或双加成物 N,N′-乙烯双和 N,N′-邻苯双[3-氨基亚甲基-2-羟基-2-(三氟甲基)色满-4-酮]。
