Reactions of aromatic and heteroaromatic β-amino-β-polyfluoroalkylvinyl ketones with ethylenediamine. A new synthesis of N,N′-unsubstituted imidazolidines

Article abstract of DOI:10.1007/BF02496176

The reactions of aromatic and heteroaromatic β-amino-β-polyfluoroalkylvinyl ketones with ethylenediamine results in the formation of 2,3-dihydro-1H-1,4-diazepines, N,N′-unsubstituted imidazolidines, or N,N′-ethylenebis(aminovinyl ketones). The reaction route depends on the reaction conditions, the nature of the substituent at the carbonyl group, and the number of fluorine atoms in the polyfluoroalkyl radical.
