Abstract
A group of polyfluoroaldehydes represented by 3,3,3-trifluoropropanal can be formed with very good selectivity by reacting polyfluoroalkenes represented by 3,3,3-trifluoropropene with water in the presence of a source of divalent palladium. A group of polyfluoroacetals represented by 1,1-dialkoxy-3,3,3-trifluoropropane can be formed with very good selectivity by reacting the same polyfluoroalkenes with an alcohol in the presence of a source of divalent palladium.
