Abstract

Bu çalışmada, N-heterosiklik karben (NHC) ligandı içeren yeni palladyum kompleksleri

sentezlendi ve yapıları 1H NMR, 13C NMR ve element analizi yöntemleri ile karakterize edildi.

Palladyum-NHC komplekslerinin katalitik aktivitesi, mono-florobenzenlerin çeşitli aril bromürler ile

direkt arilasyonu tepkimelerinde test edildi. Palladyum-NHC kompleksleri, elektron verici ve elektron

çekici aril bromürler için yüksek katalitik aktivite gösterdi.

Synthesis of Novel Palladium-N-Heterocyclic Carbene Complexes and Their Catalytic Application in the Direct Arylation of Mono-Fluorobenzenes

Abstract

In this study, novel palladium complexes containing N-heterocyclic carbene (NHC)

ligands were synthesized and their structures characterized by 1H NMR, 13C NMR and elemental

analysis techniques. The catalytic activities of palladium-NHC complexes were tested in the direct

arylation reactions of mono-fluorobenzenes with various aryl bromides. Palladium-NHC complexes

showed the high catalytic activity for electron-donating and electron-drawing aryl bromides.

Keywords

N-Heterocyclic carbene, palladium, direct arylation, fluorobenzene
