KARIPCIN, FATMA  and  ARABALI, FILIZ. SYNTHESIS AND CHARACTERIZATION OF 4-ARYLAMINOBIPHENYLGLYOXIMES AND THEIR COMPLEXES. J. Chil. Chem. Soc. [online]. 2006, vol.51, n.3, pp. 982-985. ISSN 0717-9707.  doi: 10.4067/S0717-97072006000300012.

4-Chloroacetylbiphenyl has been synthesized by Friedel-Crafts reaction between biphenyl and chloroacetyl chloride in the presence of AlCl₃ catalyst. The nitrosation reaction of this compound gave 4-biphenylhydroxamyl chloride (HL). Subsequently, 4-biphenylchloroglyoxime (H₂L) was prepared by the reaction of 4-biphenylhydroxamyl chloride and hydroxylamine hydrochloride. Then, six new substituted 4-biphenylaminoglyoximes (H₂L^x) have been synthesized from 4-biphenylchloroglyoxime and the corresponding amines. A series of M(II)-dioxime complexes of the type [M(HL^x)₂] or [M(HL^x)₂(H₂O)₂] [M(II)=Co(II), Ni(II), Cu(II)] have been synthesized and characterized by FT-IR, ¹H NMR spectral studies, elemental analysis, AAS and magnetic susceptibility measurements
