Benzoyl thiourea synthesis, preparation of thiourea
The proposed structures given in Scheme 1 are consistent with the analytical and spectroscopic data.
Acetone and dichloromethane used without further purification. The C8—N2 and C7—N1 bonds also indicate a partial double bound character. The thiourea moiety is almost perpendicular to the phenyl ring plane with an angle of Molecular structure of HL1.
Abstract New benzoyl thiourea derivatives and their nickel and copper complexes were synthesized. Only four of the synthesized compounds were suitable for X-ray single crystal diffraction.
Therefore, new thiourea derivatives and their structures have received attention of several research groups because of their complexation capacity [ 2 — 5 ]. The molecules of compounds HL1 and HL4 are effectively nonplanar, as shown by the values of the N1—C7—C1—C6 torsion synthesis, respectively, Table 2 ; this synthesis defines the rotation of the aryl ring relative to the rest of the molecule.
All the other bond lengths fall within the expected ranges [ 34 ]. All IR spectra of metallic complexes are practically similar.
All this thioureas are in agreement with the literature [ 1112212224 — 28 ]. The solid product was washed with water and purified by recrystallization from an ethanol: Synthesis of the ligands. A metal acetate solution in methanol was added dropwise to penile prosthesis replacement ligand in a 1: Four of the synthesized compounds are analyzed by X-ray single crystal diffraction technique.
The 1H NMR spectrum of ligands exhibited broad signals at 8. General Procedure for the Synthesis of Metal Complexes The metal complexes were prepared according to a described method [ 21 — 23 ].
Crystal and molecular structures of three synthesized ligands and one metal complex were analyzed by X-ray single crystal diffraction method. Some derivatives are biologically active, such as antifungal [ 67 ], antitumour [ 8 — 10 ], antiviral, antibacterial [ 11 — 13 ], pharmacological [ 14 ], herbicidal, and insecticidal properties [ 11 — 13 ].
