The Mn(III) atom in the title complex, [Mn(C(13)H(9)N(3)O(2))(C(5)H(7)O(2))(H(2)O)], is coordinated by three donors from a dianionic ligand, salicylaldehyde nicotylhydrazone, two O atoms from an acetyl-acetonate anion and a water mol-ecule in a distorted octa-hedral geometry. There is an extended two-dimensional supra-molecular motif resulting from O-H⋯N hydrogen bonds between the coordinated w...

Oxazoline is one of the 5 membered heterocycle ring can be synthesized in many ways and various activities like analgesic, antimicrobial and antidiabetic activity are well documented. In the present study analgesic activity screened by tail flick and tail immersion model.The synthesized compounds are ideally characterized spectrophotometrically. Chlorinated and methoxylated oxazolines found to ...

The title chiral photochromic Schiff base compound, C(16)H(17)NO(2), was synthesized from (R)-1-phenyl-ethyl-amine and 5-methoxy-salicylaldehyde. The mol-ecule of the title compound exists in the phenol-imine tautomeric form. The dihedral angle between the two aromatic rings is 62.61 (11)°. An intra-molecular O-H⋯N hydrogen bond with an O⋯N distance of 2.589 (2) Å is observed. The crystal packi...

Using the water eliminated mechanism, reactions of 4-pyridinecarboxylic acid hydrazide and salicylaldehyde, benzaldehyde, cinnamaldehyde, and formaldehyde afforded the corresponding N(4)[(E)-1-(2-hydroxyphenyl) methylidene] (NHPM), N(4)-[(E)-2-phenylethylidene] (NPI), N(4)[(E,2E)-3-phenyl-2-propenylidene] (NPPI), and N(4)[(E) ethylidene] (NEI) isonicotinohydrazide, in high yields, after several...

Amino-functionalised metal-organic frameworks UiO-66 and -67 were post-synthetically modified with salicylaldehyde. A molybdenum complex was immobilised on the resulting materials. They were characterised by (13)C-MAS-NMR, XPS and PXRD to confirm immobilisation and stability. The immobilised complex is an active and reusable catalyst for olefin epoxidation with tert-butyl hydroperoxide (TBHP) a...

condensation of aromatic aldehydes with benzoyl acetone under specified conditions yieldedtwo series of polycarbonyl compounds in which the keto group is attached to olefinic linkage.spectral and analytical data revealed the formation of an unsaturated triketone from pyridine-3-carbaldehyde and unsaturated diketone from furfural, salicylaldehyde and 2-hydroxynaphthaldehyde. analytical, ir, 1h n...
