Through the esterification of cellulose (Cell) with ethylenediaminetetraacetic dianhydride, acid-functionalized (Cell-EDTA) was conveniently obtained. Furtherly a novel and efficient Cell-EDTA-supported palladium catalyst (Pd@Cell-EDTA) easily prepared via coordination Cell-EDTA PdCl2. The as-prepared Pd@Cell-EDTA fully characterized by inductively coupled plasma atomic emission spectrometry, X...

Two Ag-Pd (nominal 1 % wt each) bimetallic catalysts supported on commercial activated carbon were synthesized and tested, for the first time, in hydrodechlorination (HDC) of trichloromethane (TCM) to obtain light olefins. different Pd precursors used, PdCl2 Pd(NO3)2, being resulting denoted as AgPdCl/C AgPdN/C, respectively. A monometallic Ag catalyst was also prepared comparison purposes. The...

The chiral ligand (-)-sparteine and PdCl(2) catalyze the enantioselective oxidation of secondary alcohols to ketones and thus effect a kinetic resolution. The structural features of sparteine that led to the selectivity observed in the reaction were not clear. Substitution experiments with pyridine derivatives and structural studies of the complexes generated were carried out on (sparteine)PdCl...

The synthesis of several carbazole-bis(triazole) (CzTrR) and carbazole-bis(tetrazole) (CzTR) ligands (5a–d 6a–d, respectively, where R=Me (a), i–Pr (b), Bz (c) CH2-2,4,6-C6H2Me3 (d)) is reported. Reaction these with PdCl2 in refluxing acetonitrile affords the complete series square planar complexes, Pd(CzTrR)Cl (7a–d) Pd(CzTR)Cl (8a–d). analogous platinum complexes are prepared by deprotonation...
