N-Alkilleme ve yük transfer kompleks çalışmaları

Abstract

Organik kökenli hetero atom ihtiva eden amin, amit ve türevleri; gübre, ilaç,deterjan, insektisit gibi bir çok alanda kullanım sahalarına sahiptir. Bu çalışmadahetero atom ihtiva eden ve yüksek delokalizasyona sahip olan aminlerinN-alkillenme reaksiyonları incelenmiştir.Denemler sonucunda N-(9-antrilmetil)N,N',N?-Tri(1-naftilmetil)melamin,iminodibenzil, N-(1-naftilmetil) iminodibenzil, N-(benzil)indol, N-(benzil)fenotiazinve N-(1-naftilmetil)fenotiazin bileşikleri sentezlendi ve yapıları NMRspektroskopisi ile aydınlatıldı.Sentezlenen bileşiklerden N,N',N?-Tri(1-naftilmetil)melamin ile DDQ ve TCNEarasında eloktron donor akseptör komplekslerinin oluşumu spektrofotometrik olarakincelendi.

Organic based amine, amide and its derivatives which contains heteroatom, can beused in many areas, like fertilization, medicine, detergent and insecticide. In thisstudy, N-alkylation reactions of amines which have high delocalization and containsheteroatom were investigated.N,N?,N?-Tri(1-napthylmethyl)melamine, N-(9-antrylmethyl)iminodibhenzyl, N-(1-napthylmethyl)iminodibenzyl, N-(benzyl)indole, N-(benzyl) phenothazine and N-(1-napthylmethyl)phenothazine were synthesized and their structures were analyzed byNMR spectrophotometer.Electron donor acceptor (EDA) complexes of N,N?,N?-Tri(1-napthylmethyl)melamine as electron donors with DDQ and TCNE as electron acceptors have beenexamined spectrophotomethrically. Stochiometries of the complexes weredetermined by Job?s Method. Equilibrium constants of the complexes werecalculated by Benes-Hildebrand equation. Thermodynamic constants of thecomplexes were calculated by Van?t Hoff equation.EDA complexes of N,N?,N?-Tri(1-napthylmethyl)melamine-DDQ gave amaximum absorption at 573 nm. Equilibrium constant of the complex is 31,99 Lmole-1, thermodynamic constants of the complex â H:-1493 cal moel-1, â S:-8,58 calmole-1 and â G°: -4007,83 cal mole-1. EDA complexes of N,N?,N?-Tri(1-naftilmetil)melamin-TCNE gave a maximum absorption at 576 nm. Equilibriumconstant of the complex is 7,89 L mole-1, thermodynamic constants of the complexâ H:-1987 cal mole-1, â S:-11,97 cal mole-1 and â G°: -1206,51 cal mole-1 dir.
