A molecularly defined NiII -complex catalyzing the chemoselective acetalization of aldehydes with alcohols under neutral conditions is reported. The reaction is general, efficient and showed a wide substrate scope (including aliphatic aldehydes) as well as excellent functional group tolerance. Reusability of the present nickel catalyst is also demonstrated.
Keywords: acetalization; alcohols; aldehydes; homogeneous catalysis; nickel.
