Abstract
The alkyl acrylates, e.g., methyl or ethyl acrylate, are improvedly dimerized, or codimerized with a conjugated diene, by contacting same with a catalytically effective amount of (a) at least one palladium source, (b) at least one organophosphorus(III) compound, and (c) at least one hydracid HY, the anion Y.sup.- of which does not coordinate with palladium ions.
