This work involves synthesis of different five and six member heterocyclic rings starting from phenyl acetic acid. This work is divided into four different parts:
First part:
This part involved the synthesis of phthalazin-3,8-dione [7] and pyridazin-3,6-dione [6], pyrazole [4,5] and thiadiazole[8] derivative derived from phenyl acetyl hydrazide[3] . as shown in scheme I.
Second part:
This study concened with the study of solute-solvent interaction of vitamins:[Ascorbic Acid,pantothenic Acid,Folic acid,Thiamine and Pyridoxne] as solutes in water and in hydrochloric acid solution (0.1 mol.L 1) as solvents This study coverd experimental measurements using Anton Paar (DMA 60/602) densimeter, as well as theoretical caculatoins concerning partial molal volume, and some related parameters,a comparison and discussion was made in the light of these mesurements.
A new ligand have been prepared in this work, which was chosen to synthesis a new set of transition metal complexes [Mn(ІІ),Co (II), Ni (II),Cu(ІІ),Zn(ІІ),Hg (II),Cd (II),Pd(ІІ), Cr(ІІІ) and Rh (IІI)].
