Abstract
New substituted asymmetrically imidazolium salts with Ag(I) and Pd(II)
N-heterocyclic carbene complexes were synthesized and characterized. In order to
produce asymmetrically substituted salts, imidazolium salts have been produced using
a variety of substituents, including aliphatic chain and phenyl acetamide chloride
(5,6,7). Using the carbene site deprotonation process, silver(I)-NHC complexes
(8,9,10) were produced from the reaction of asymmetrically substituted imidazolium
salts with Ag2O. The appropriate Pd(II)-NHC (11,12,13) were then synthesized using
the transmetallation process using Ag(I)-complexes. NHC as transfer reagents. The
complexes were identified using spectroscopy methods such as 1H-,
13C-NMR and
FT-IR spectroscopy. The recorded spectra of the prepared complexes and their salts
agree with theoretical ones.
