Synthesis, Structural Characterisation and Biological Activity; New Metal Complexes Derived from Semicarbazone Ligand
...Show More Authors

The results of synthesizing a novel tridentate Schiff-base ligand and its metal complexes have been given. The ligand itself is described as being tridentate. The synthesis of the ligand has the following chemical formula: (E)-2- ((2S)-4-(tert-butyl) -2-((S)-(phenylamino) (p-tolyl) methyl) cyclohexylidene) hydrazine -1-carboxamide was produced as a byproduct of the reaction between benzoic acid and benzoic acid between (((4-(tert-butyl)-2-((S)-(phenylamino)(p-to and (HL). The ligand was reacted with 1:1 (L:M) mole ratios of ions containing Mn(II), Co(II), Ni(II), Cu(II), Zn(II), and Cd(II), which resulted in the production of title complexes. In cases where it was necessary, physicochemical techniques were utilized to characterize both the ligand and the complexes. Examples include magnetic susceptibility and conductance measurements, microanalysis of elements, nuclear magnetic resonance (1H, 13C), mass spectrometry, Fourier transform infrared (FT-IR), electronic spectra, and more. The results of these studies demonstrated that the ions Mn (II), Co (II), Cu(II), Ni(II), Zn(II), and Cd(II) can be partitioned into four-coordinate and six-coordinate complexes, respectively. In addition, the TGA was used to investigate whether or not the ligand and specific complexes were thermally stable. Several different bacterial and fungus strains were utilized to examine the ligand and its complexes for potential antibacterial activity. According to the findings, the complexes are far more effective than the free ligand in combating a wider variety of species.

New Fourteen compounds were synthesized in four steps. The first step included synthesis of 2-biphenyl fused ring of imidazo(1,2- a)pyrimidine from the reaction of 2-aminopyrimidine and biphenyl phenacyl bromide . The second step was introduced aldehyde group from the reaction of 2-biphenyl fused rings of imidazo(1,2-a)pyrimidine with POCl3 in presence of DMF and CHCl3. 3-Carbaladehyde derivatives of fused imidazo/pyrimidine was reacted with different aromatic amines to afford new Schiff bases. These new 3- imines derivatives was reduced by using sodiumborohydride to yield another new 3-aminomethyl-2-biphenyl imidazo (1,2-a)pyrimidine derivatives in moderate yield .Some new prepared compounds were identified by melting point, FT- IR , 13C-

Coupling reaction of 2-amino benzoic acid with 8-hydroxy quinoline gave bidentate azo ligand. The prepared ligand has been identified by Microelemental Analysis,1HNMR,FT-IR and UV-Vis spectroscopic techniques. Treatment of the prepared ligand with the following metal ions (ZnII,CdII and HgII) in aqueous ethanol with a 1:2 M:L ratio and at optimum pH, yielded a series of neutral complexes of the general formula [M(L)2]. The prepared complexes have been characterized by using flame atomic absorption, (C.H.N) Analysis, FT-IR and UV-Vis spectroscopic methods as well as conductivity measurements. The nature of the complexes formed were studied following the mole ratio and continuous variation methods, Beer's law obeyed over a concentration ra
