چکیده
In the title ylide, C(31)H(28)ClO(2)P [common name α-acetyl-α-p-chloro-benzoyl-methyl-enetri(p-tol-yl)phospho-rane], the dihedral angle between the 4-chloro-phenyl ring and that of the ylide moiety is 66.15 (10)°. The geometry around the P atom is slightly distorted tetra-hedral [angle range = 105.22 (8)-115.52 (9)°] and the carbonyl O atoms are syn-oriented with respect to the P atom. The ylide group is close to planar [maximum deviation from the least-squares plane = 0.006 (2) Å] and the P-C, C-C and C=O bond lengths are consistent with electron delocalization involving the O atoms.

In the title compound, [Al(C(8)H(4)F(3)O(2)S)(3)](3)[Fe(C(8)H(4)F(3)O(2)S)(3)], the metal centre is statistically occupied by Al(III) and Fe(III) cations in a 3:1 ratio. The metal centre is within an octa-hedral O(6) donor set defined by three chelating substituted acetoacetonate anions. The ligands are arranged around the periphery of the mol-ecule with a mer geometry of the S atoms.

متن کاملImpact of aromatic substitution on the anticonvulsant activity of new N-(4-arylpiperazin-1-yl)-alkyl-2-azaspiro[4,5]decane-1,3-dione derivatives.
A series of N-[(4-arylpiperazin-1-yl)-alkyl]-2-azaspiro[4.5]decane-1,3-dione derivatives were synthesized and evaluated for their anticonvulsant and neurotoxic properties. The main modifications to that series of compounds consisted in the introduction of an aromatic area to the cyclohexane ring as a flexible fragment with conformational freedom (1a-h), or as a rigidified skeleton (2a-h). Excep...
