alkenes via intermediate organopalladiumcomplexes are discussed. The oxidation of propylene, hex-1-ene and cyclohexene by PdII acido complexescontaining achiral, racemic and chiral carboxylate ligands was first studied in a series of solvents other than acetic acid. Significant changes in the selectivity of the PdII-promoted reaction with changes in the solvent nature and ligand chirality were observed

The effects of the solvent and the ligand chirality on the regioselectivity of oxidative esterification of propylene and cyclohexene by PdII carboxylates were studied using achiral (MeCO2−, Me2CHCH2CO2−), racemic ((±)-CF3CF2CF2OC*F(CF3)CO2−), and chiral ((S)−(+)−MeC*H(Et)CO2−, (+)−CF3CF2CF2OC*F(CF3)CO2−) carboxylate ligands. The oxidation of alkenes in aprotic media (CHCl3, CH2Cl2, CO2, THF) affords
