REACTIONS OF ORGANOALUMINATES WITH COPPER(II) ACETATE IN THE ABSENCE OR IN THE PRESENCE OF CARBON MONOXIDE. A CONVENIENT METHOD FOR CONVERSION OF OLEFINS INTO THEIR SATURATED DIMERS OR KETONES
Hydroalumination of olefins with lithium alurinum hydride followed by treatment with copper(II) acetate results in the formation of the coupled products. When the reaction of organoaluminates with copper(II) acetate is carried out under a carbon monoxide atmosphere, ketones are obtained, suggesting the formation of an alkyl-copper intermediate in this reaction. This new development provides a convenient method for the conversion of clefin derivatives into their dimers or ketones.
