Abstract :In the present work, firstly the novel mono oxime insert ignore into journalissuearticles values(1); and asymmetric dioxime ligand insert ignore into journalissuearticles values(LH 2 ); insert ignore into journalissuearticles values(2); derived 4′-hydroxyvalerophenone as ketone were prepared under optimum conditions. Then, the bis-dioxime-based and boronic acid-capped groups containing Feinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(II); complexes [insert ignore into journalissuearticles values(L); 2 Minsert ignore into journalissuearticles values(X); 2 insert ignore into journalissuearticles values(BA); 2 ] insert ignore into journalissuearticles values(3-6); insert ignore into journalissuearticles values(L= Dioxime, M = Feinsert ignore into journalissuearticles values(II); or Coinsert ignore into journalissuearticles values(II);, X= Cl 2 or H 2 O and BA = Butyl boronic acid insert ignore into journalissuearticles values(BBA); or Ferrocene boronic acid insert ignore into journalissuearticles values(FBA);); were synthesized in a two-necked round-bottom reaction flask by direct contact of dioxime ligand insert ignore into journalissuearticles values(2); , and different boronic acid with metal salts insert ignore into journalissuearticles values(FeCl 2 .4H 2 O or CoCl 2 ); without special requirement of any additional chemical process. The prepared ligands and its Feinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(II); complexes were characterized by means of NMR spectra, FT-IR spectra, UV-Vis spectra, LC-MS, melting point and magnetic susceptibility measurements as well as elemental analysis. The spectroscopic results demonstrated that the proposed Feinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(II); complexes are a six-coordinated species and octahedral geometry. The infrared spectra insert ignore into journalissuearticles values(FT-IR); of the Feinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(II); complexes indicated the characteristic peak at range 1208-1217 cm -1 cm corresponding υinsert ignore into journalissuearticles values(B-O); stretching.
