Abstract:

Transition-metal-catalyzed olefin isomerization has played a crucial role in the synthesis of organic compounds, commodity chemicals, natural products, and petroleum feedstocks. Although noble metals such as Ru, Rh and Ir as catalysts for the conversions have made dramatic achievements, the disadvantages of the rare resource, high cost, and poisoning products have limited its wide application in the synthesis. Due to the abundant supply, low cost and easy removal from the final products, the first-row transition metals have attracted much attention from the chemists and have proven to be very promising with respect to the development of more sustainable catalytic system in olefin isomerizaton. This review summaried the advances in olefin isomerization catalyzed by iron, cobalt, nickel in the past years and illustrates the differences among different catalytic systems in catalytic activity, regio- and stereo-selectivity, and substrate scope. Recent developments in the olefin isomerization catalyzed by the first-row metals have proven to be very promising and effective. The reaction mechanism was discussed to have deep insight into the isomerization. The mechanism of olefin isomerization was illustrated clearly in the reported articles through intermolecular or intramolecular hydrogen shift, and the stereoselectivity and regioselectivity in different catalytic system was still worthy of further investigations. Further studies in the field to solve the challenges in high catalytic activity, stereoselectivity, and wide substrate scopes would bring the isomerization into better prospect.

Key words: olefin isomerization, transition metals, regioselectivity, stereoselectivity, catalysis
