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

clathrate-like hydrates. The results can be summarized as follows: (1) for 14 carboxylates the formation of a clathrate-like hydrate is newly confirmed; (2) judging from melting points and hydration numbers, the hydrates can be classified into three groups: I, II, and III; (3) the group I hydrates, formed by the carboxylates with R=H, CH3, C2H5, n-C3H7, i-C3H7, and t-C4H9, have hydration numbers around
