  Synthesis of (4-arylpyrrolidin-2-ylidene) derivatives of cyclic β-dicarbonyl compounds from cinnamoyl precursors

  摘要：

  1,4-Conjugate Michael addition of nitromethane to the enone fragment of cinnamoyl derivatives of carbo- and heterocyclic beta-dicarbonyl compounds provided the corresponding nitromethyl derivatives. The chemoselective reduction of the nitro group in the latter afforded 4-arylpyrrolidin-2-ylidene derivatives of beta-dicarbonyl compounds in high yield. The reaction products with the heterocyclic beta-dicarbonyl fragment are formed as equilibrium mixture of E- and Z-rotamers in which the E-rotamer predominates.

  Platinum(II) cationic complexes with derivatives of 2-acyl-1,3-cyclopentanedions

  摘要：

  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.
