Methods of Making Functionalized Internal Olefins and Uses Thereof
Abstract
A method of isomerizing a substance includes combining a substance including a terminal alkenyl group and a substance including a fluorosulfonic acid group in a reaction mixture, and forming a substance including a 2-alkenyl group from the substance including a terminal alkenyl group in the reaction mixture. The method may be used to functionalize a substance, as the substance including a 2-alkenyl group can be reacted with a functionalizing agent to form a substance including a first functional group. The methods may be used to form a dicarboxylic acid, such as suberic acid, from a renewable feedstock.
