Mono- and Bimetallic Complexes of Mn(Ii), Co(Ii), Cu(Ii), and Zn(Ii) With Schiff Bases Immobilized on Nanosilica as Catalysts in Ozone Decomposition Reaction

The results of the study of catalytic activity of nanocomposites containing mono- and bimetaliic manganese(II), cobalt(II), copper(II), and zinc(II) complexes with Schiff bases [(salicyl-aldiminopropyl (L1) and 2-hydroxy4-methoxybenzophenoniminopropyl (L2)] immobilized on silica in the reaction of ozone decomposition are presented. The catalytic activity dependence on a nature of complexing metal ions and ligands has been determined.

Synthesis, Characterization and Antimicrobial Activity of New Nucleoside Analogues from Benzotriazole

Novel derivatives of 1-(´1, ´3, ´4, ´6-tetra benzoyl-β-D-fructofuranosyl)-1H- benzotriazole and 1-(´1, ´3, ´4, ´6-tetra benzoyl-β-D-fructofuranosyl)-1H-benzotriazole carrying Schiff bases moiety were synthesised and fully characterised. The protection of D-fructose using benzoyl chloride was synthesized, followed by nucleophilic addition/elimination between benzotriazole and chloroacetyl chloride to give 1-(1- chloroacetyl)-1H-benzotriazole. The next step was condensation reaction of protected fructose and 1-(1-chloroacetyl)-1H-benzotriazole producing a new nucleoside analogue.
