Synthesis and Studies Pd(II)-NHC complexes with thiosaccharinate, saccharinate or benzothiazolinate ligands

Three cis-chelating di-N-heterocyclic carbene palladium(II) complexes [Pd(X)2(di- NHC)] (X= tsac, sac and bit) tsac= thiosaccharinate, sac= saccharinate, bit= benzisothiazolinate, bearing different anionic co-ligand was synthesized characterized. A series of (2-5) homo-dicarbene ligand with varying propylene-bridged (C3) N-heterocyclic backbones (imidazole) have been by reaction [Pd(OAc)2] the respective diazolium bromides in DMSO, prepared characterized elemental analysis, infrared spectra 1H NMR. These compounds are all stabilized sold state. The bidentate (diNHC) together two N-coordenated , bit S-coordenated tsac ligand, from square planar coordination geometry around ion.
