چکیده
A new se ries of tricarbonyl com pounds, in which the keto groups are at tached to olefinic link ages, have been syn the sized by the re ac tion be tween acetoacetanilide and ar o matic al de hydes (2-chlorobenzaldehyde, 4-chlorobenzaldehyde, 4-hydroxybenzaldehyde and vanillin) un der spec i fied con di tions. Their IR, H NMR and mass spec tral data re vealed that only one of the car bonyl groups is enolised and en gaged in intramolecular hy dro gen bond ing. Neu tral bidentate co or di na tion of these com pounds with Ni(II), Cu(II) and Zn(II) has been es tab lished on the ba sis of an a lyt i cal and spec tral data.

Spiroheterocyclization of methyl 1-aryl-3-cinnamoyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates by the action of 3-(arylamino)-1H-inden-1-ones.
Methyl 1-aryl-3-cinnamoyl-4,5-dioxo-4,5-dihydro-1H-pyrrole-2-carboxylates interact with 3-(arylamino)-1H-inden-1-ones to give the corresponding 1,1'-diaryl-3'-cinnamoyl-4'-hydroxy-1H-spiro[indeno[1,2-b]pyrrole-3,2'-pyrrole]-2,4,5'(1'H)-triones in good yields.

متن کاملRational design of 1-D metal-organic frameworks based on the novel pyrimidine-4,6-dicarboxylate ligand. New insights into pyrimidine through magnetic interaction.
Single crystal X-ray analysis of compounds H2pmdc.2H2O (1), KHpmdc (2), and K2pmdc (3) shows that the pyrimidine-4,6-dicarboxylate (pmdc) dianion presents an almost planar geometry which confers a potential capability to act as a bis-bidentate bridging ligand, and therefore, to construct 1-D metal complexes. Based on this assumption, we have designed the first six transition metal complexes bas...
