Synthesis and Characterization of Unsymmetrical Schiff Base and Transitıon Metal Complexes

Abstract

In this study, firstly, monoimine compound (H3A) was synthesized from the condensation of 2-aminobenzylamine and 1’-hydroxy-2-acetonaphthone which is a ketone derivative. Asymmetric Schiff base (H2L) was synthesized as a result of the condensation of the obtained H3A and 5-bromosalicylaldehyde. After that, the synthesis and characterization of the Cu(II), Ni(II), Co(II) and Fe(III) complexes of the synthesized H2L compound were carried out. The proposed structures of Schiff bases and its metal complexes were elucidated using analytical and spectroscopic (UV-Vis, FT-IR, elemental, 13C and 1H NMR, LC-MS, ICP-AES, magnetic susceptibility, molar conductivity, and TG-DTA) methods.

Asimetrik Schiff Bazı ve Geçiş Metal Komplekslerinin Sentezi ve Karakterizasyonu

Abstract

Bu çalışmada önce 2-aminobenzilamin ile keton türevi olan 1'-hidroksi-2'-asetonaftonun kondenzasyonundan monoimin bileşiği (H3A) sentezlenmiştir. Elde edilen H3A ile 5-bromosalisilaldehitin kondenzasyonu sonucu asimetrik Schiff bazı (H2L) sentezlenmiştir. Daha sonra sentezlenen H2L bileşiğinin Cu(II), Ni(II), Co(II) ve Fe(III) komplekslerinin sentezi ve karakterizasyonu gerçekleştirilmiştir. Schiff bazı ve metal komplekslerinin yapıları analitik ve spektroskopik yöntemler (UV-Vis, FT-IR, elementel, 13C ve 1H NMR, LC-MS, ICP-AES, manyetik suseptibilite, molar iletkenlik ve TG-DTA) kullanılarak aydınlatılmıştır
