Schiff bases

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.

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.
