Abstract
A method for preparing cuprous carboxylates (Cu(I) carboxylates) is provided wherein Cu(II) carboxylates are reacted with copper powder in an aromatic solvent under a reducing atmosphere, optionally in the presence of at least one of a carboxylic acid or carboxylic acid anhydride. Also, a method for preparing desired Cu(II) carboxylates is provided wherein a Cu(II) carboxylate having fewer carbon atoms is reacted with a carboxylic acid corresponding to the desired Cu(II) carboxylate. The invention method reactions achieve good conversions with rapid rates of reaction. The Cu(I) carboxylates produced according to the invention method are useful as reagents or in the preparation of olefin complexing reagents.
