Abstract

Palladium (I) carbonyl carboxylate complexes [Pd (μ-CO)(μ-RCO2)] n (R= Me, n= 4; R= CMe3, n= 6) and the corresponding palladium (II) carboxylates (acetate and pivalate) catalyze the cyclopropanation of olefins with ethyl diazoacetate. The performance of these catalysts is similar in terms of selectivity and cyclopropane yields, regardless of the oxidation state of the metal center. However the rates of the cyclopropanation reactions are ...
