Abstract:
A method for producing ethers comprises the following steps:initiating telomerization process of a conjugated diene compound with an hydroxyl compound represented by the following formula (I): R1OH (I) in the presence of a palladium compound, a tertiary isocyanide represented by the following formula (II): R2NC (II), and a base; and adding halfway through the telomerization process a tertiary phosphine represented by the following formula (III): PR3R4R5 (III) (the respective symbols are defined in the description).
