Acetalization of alkenes catalyzed by Pd(OAc)2/NPMoV supported on activated carbon under a dioxygen atmosphere
[reaction: see text] The acetalization of terminal alkenes such as ethyl acrylate and acrylonitrile with alcohols under O2 was efficiently achieved by Pd(OAc)2 supported on activated carbon combined with molybdovanadophosphate (NPMoV). For example, ethyl acrylate was subjected to acetalization with EtOH acidified by CH3SO3H under O2 (1 atm) in the presence of [8 wt%Pd(OAc)2/C] and NPMoV to form ethyl 3,3-diethoxypropionate in quantitative yield.
