Abstract
A method for producing a boron-containing compound comprises a step of reacting a first raw material compound having a carbon-carbon double bond with a second raw material compound having a conjugated diene skeleton in the presence of a metal catalyst to obtain a boron-containing compound having a 1,4-diene skeleton, wherein at least one of the first raw material compound and the second raw material compound has a boron-containing group bonded to a carbon atom constituting the carbon-carbon double bond or the conjugated diene skeleton, and the boron-containing compound has the 1,4-diene skeleton and the boron-containing group.
