Catalysis of Pd(II)-catalyzed acetalization of alkenes with diols

Article abstract of DOI:10.1246/bcsj.63.166

Alkenes bearing electron-withdrawing substituents are catalytically acetalized with 1,3-propanediol only by the use of PdCl₂(MeCN)₂ catalyst under O₂ atmosphere. When a combination of BiCl₃ and LiCl is used as co-catalyst, the acetalization proceeds effectively. These results indicate that a hydroperoxopalladium(II) species is most likely an active catalyst in the present reaction.
