Synthesis of palladium complexes derived from imidazolidin-2-ylidene ligands and used for catalytic amination reactions
(Wiley, 2016)
N-Aryl amination and the Buchwald-Hartwig reaction are of great synthetic and industrial interest and scientists accept their usefulness and versatility for obtaining arylamines. In this study Ag-N-heterocyclic carbene ...
Novel ruthenium(II)-N-heterocyclic carbene complexes; synthesis, characterization and catalytic application
(Elsevier Science Sa, 2015)
The synthesis of highly active ruthenium(II) catalyst based on N-heterocyclic carbene (NHC) bearing alkyl and aryl groups is reported. The complexes are easily handled in very good yields via synthesis of silver -NHC ...
Synthesis and Catalytic Activity of Novel Benzimidazolinylidene-Ruthenium(II) Complexes
(Georg Thieme Verlag Kg, 2010)
The reaction of [RuCl2(p-cymene)](2) with 1,3-dialkyl-benzimidazolium salts 1a-d in the presence of a small excess of cesium carbonate yields chelated eta(6)-arene, eta(1)-carbene ruthenium complexes 2a-d. All compounds ...
Palladium N-heterocyclic carbene complexes: Synthesis, characterization and catalytic properties in amination
(Elsevier Science Sa, 2010)
Transmetalation has proved to be a promising procedure to obtain NHC-metal complexes, which typically involves treatment of the imidazolium salt with Ag2O to form the Ag-NHC complex, followed by transmetalation to a species ...
Synthesis and structural characterization of two novel N-heterocyclic carbene complexes of Rh(I)
(Taylor & Francis Ltd, 2007)
Two new N-heterocyclic carbene (NHC) ligands with p-methylphenyl and p-methoxyphenyl substituents on 4,5-positions and methoxyethyl pendants on N atoms of the imidazole ring were complexed together with cyclooctadiene and ...
Imidazolium salicylaldimine frameworks for the preparation of tridentate N-heterocyclic carbene ligands
(Elsevier Science Sa, 2008)
Sterically hindered salicylaldimine functionalized imidazolium salts 2 have been prepared. The structures of the synthesized compounds were determined by spectroscopic techniques. The reaction of these salts containing ...
