Sugar hydrazones 4-7 were prepared through condensation of the respective sugars (D-glucose, D-mannose, D-galactose, and D-arabinose) with (3-hydrazono-2-oxo-2,3-dihydroindol-1-yl)acetic acid hydrazide 3 which was prepared from the reaction between hydrazine hydrate and (2,3-dioxo-2,3-dihydro-indol-1-yl)acetic acid ethyl ester 2. Acetylation of 4-7 afforded the per-O-acetylsugar-N-acetylhydrazones 8-11. Cu(II), Zn(II), Mn(II) and Fe(III) complexes of the glucose derivative 4 [HL] were prepared and characterized by elemental analysis, conductivity measurements, IR, UV-Vis. and magnetic moment measurements. TGA and DTA confirm the chemical formulation of the complexes and their thermal decomposition were evaluated.
