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

cis-Diammineplatinum(II) complexes containing 2-acyl-1,3-cyclopentadion fragments as a bidentate acido ligand were prepared by the transformation of cis-diamminediiodoplatinum(II) to cis-diamminesulfatoplatinum(II) under the action of silver sulfate with the subsequent treatment of the resulting complex by barium hydroxide and by the reaction of the synthesized base with a twofold amount of 2-acyl-1,3-cyclopentanedion. The products are the cationic complexes of cis-diammineplatinum(II) and contain 2-acyl-1,3-cyclopentanedionate as a bidentate acido ligand, which chelates platinum atom by the carbonyl groups of side acyl chain and one group connected with five-membered cycle, whereas a 2-acyl-1,3-cyclopentadion enolate anion forms counter ion.
