Preparation of fluorine-containing exo- and endocyclic enamine derivatives of 2-acylcyclopentane-1,3-diones

The interaction of aromatic amines (4-fluorinebenzylamine, 3-trifluoromethylbenzylamine, 4-fluoroaniline, or 3,4-difluoroaniline) with either 2-acylcyclopentane-1,3-diones (fluorine-substituted or fluorine-free) or their enol derivatives (chlorovinyldiketones) has led to fluorine-containing exo- or endocyclic enamine derivatives of 2-acylcyclopentane-1,3-diones.
