N-heterocyclic carbene palladium complexes with different N-coordinated ligands: Comparison of their catalytic activities in Suzuki-Miyaura and Mizoroki-Heck reactions
Karatas, Mert Olgun; Özdemir, Namık; Alici, Bulent; Özdemir, İsmail (Pergamon-Elsevier Science Ltd, 2020)In this paper, we have reported the synthesis and catalytic activities of four new anthracene substituted imidazole-based palladium N-heterocyclic carbene complexes. The synthesized complexes, 2a-d, were stabilized with ... -
Novel N-Alkylbenzimidazole-Ruthenium (II) complexes: Synthesis and catalytic activity of N-alkylating reaction under solvent-free medium
Sahin, Neslihan; Özdemir, Namık; Gurbuz, Nevin; Özdemir, İsmail (Wiley, 2019)In this article, direct N-alkylation reactions of amines with alcohols derivatives have been investigated. For this purpose, a new series ruthenium (II) complexes bearing N-coordinated benzimidazole complexes with have ... -
Palladium-carbene catalyzed direct arylation of five-membered heteroaromatics
Kaloglu, Murat; Kaloglu, Nazan; Ylidirim, Ilkay; Özdemir, Namık; Özdemir, İsmail (Elsevier, 2020)Due to the industrial importance of bi(hetero)arenes, the synthesis of these compounds by homogeneous Pd-catalyzed direct arylation is an important research topic in modern organic chemistry. In this study, PEPPSI-type, ... -
Sonogashira cross-coupling reaction catalysed by mixed NHC-Pd-PPh3 complexes under copper free conditions
Touj, Nedra; Yasar, Sedat; Özdemir, Namık; Hamdi, Naceur; Özdemir, İsmail (Elsevier Science Sa, 2018)Mixed NHC-Pd-PPh3 complexes with a methoxyethyl-substituted N-heterocyclic carbene ( NHC) were synthesised and characterised by NMR, HRMS, elemental analysis and X-ray crystallography for complex 3b. These complexes were ... -
Synthesis and catalytic activity of ionic palladium N-heterocyclic carbene complexes
Yasar, Sedat; Akkoc, Mitat; Özdemir, Namık; Özdemir, İsmail (Scientific Technical Research Council Turkey-Tubitak, 2019)The synthesis of 3 benzimidazole-based ionic Pd(II)-NHC complexes (NHC: N-heterocyclic carbene) is presented. The structures of the complexes are as follows: [NHC-PdBr3](-) [NHC](+). The ionic palladium(II)-NHC complexes ... -
Synthesis, spectral, X-ray diffraction and DFT studies on 1-(2-methyl-2-propenyl)-3-(2,3,4,5,6-pentamethylbenzyl)benzimidazolium chloride hydrate
Sahin, Neslihan; Kilic-Cikla, Isin; Özdemir, Namık; Gurbuz, Nevin; Özdemir, İsmail (Taylor & Francis Ltd, 2018)A new benzimidazole based N-heterocyclic carbene (NHC) salt (1) was synthesized by the reaction of benzimidazole precursor with alkyl halide. The structure of 1 was determined by elemental analysis, FT-IR, H-1 NMR and C-13 ... -
Well-defined PEPPSI-themed palladium-NHC complexes: synthesis, and catalytic application in the direct arylation of heteroarenes
Kaloglu, Murat; Gurbuz, Nevin; Yildirim, Ilkay; Özdemir, Namık; Özdemir, İsmail (Wiley, 2020)In this study, a series of benzimidazolium salts were synthesized as unsymmetrical N-heterocyclic carbene (NHC) precursors. Benzimidazolium salts were used for synthesis of the PEPPSI (pyridine enhanced precatalyst preparation ...
