Abstract
Official abstract text for this publication.
A method for producing an ester compound including reacting a compound having at least one cyclic structure of a norbornene ring and a norbornadiene ring with an alcohol and carbon monoxide by using a palladium catalyst and an oxidizing agent, to thereby introduce ester groups to carbon atoms forming a double bond in the cyclic structure and obtain the ester compound, wherein the palladium catalyst comprises a palladium complex having a bipyridyl as a ligand.
First claim
Opening claim text (preview).
1 . A method for producing an ester compound, comprising: reacting a compound having at least one cyclic structure of a norbornene ring and a norbornadiene ring with an alcohol and carbon monoxide by using a palladium catalyst and an oxidizing agent, to thereby introduce ester groups to carbon atoms forming a double bond in the cyclic structure and obtain the ester compound, wherein the palladium catalyst comprises a palladium complex having a bipyridyl as a ligand. 2 . The method for producing an ester compound according to claim 1 , wherein oxygen is used as the oxidizing agent. 3 . The method for producing an ester compound according to claim 2 , wherein a chlorine-containing compound, a copper compound other than a chloride, and a manganese compound other than a chloride are used in combination with the oxidizing agent. 4 . The method for producing an ester compound according to claim 2 , wherein manganese chloride, copper acetate, and manganese acetate are used in combination with the oxidizing agent.
