4- (alkilaminoisonitrosoasetil) bifenil türevleri ve bunların metal komplekslerinin sentezi ve karakterizasyonu

Abstract

iiiÖZETBu çalismada ilk olarak 4-(kloroasetil)bifenil, Friedel-Crafts açillemesine görealiminyum klorür katalizörlügünde kloroasetil klorür ve bifenilden hazirlanmistir.Kuru HCl gazi varliginda 4-(kloroasetil)bifenil ile isopentil nitritin reaksiyonuyla4-bifenilhidroksimoil klorür elde edilmistir. Keto oksimin primer ve sekonderaminler ile reaksiyonundan 4-(alkilaminoisonitrosoasetil)bifenil ligandlarihazirlanmis ve ligandlar etil alkolden birkaç kez kristallendirilerek saflastirilmistir.Çalismamizda son olarak, bu ligandlarin Co(II), Ni(II), Cu(II), Zn(II), Cd(II) vePb(II) metal kompleksleri elde edilmistir. Sentezlenen ligandlarin ve komplekslerinyapilari AAS, FT-IR, 1 H NMR spektrum verileri, elementel analiz ve magnetiksusseptibilite ölçümleri ile aydinlatilmistir.ANAHTAR KELIMELER : Keto oksim, Oksim Kompleksleri, Geçis MetaliKompleksleri, Dinükleer kompleksler, Üç Disli Ligandlar

ivABSTRACTIn this study, firstly, 4-(chloroacetyl)biphenyl was prepared from chloroacetylchloride and biphenyl in the presence of alimunium chloride according to Friedel-Crafts acylation. 4-Biphenylhydroxymoil chloride was obtained by reacting4-(chloroacetyl)biphenyl with isopentyl nitrite in the presence of dry HCl gase.4-(Alkylaminoisonitrosoacetyl)biphenyl ligands were prepared from4-biphenylhydroxymoil chloride reacting with primary and secondary amines andligands were recrystallized from ethyl alcohol. Our study, finally, Co(II), Ni(II),Cu(II), Zn(II), Cd(II) and Pb(II) metal complexes of these ligands were obtained.Structures of ligands and complexes synthesized were identified with AAS, FT-IR,1H NMR spectal data, elemental analyses and magnetic susceptibility measurement.KEYWORDS : Keto oximes, Oxime Complexes, Transition Metal Complexes,Dinuclear Complexes, Three Dentate Ligands
