ABSTRACT:
According to the present invention, a method of producing ethers, which includes subjecting a conjugated diene compound and an alcohol to a telomerization reaction in the presence of a composition containing a palladium compound, an isocyanide represented by the formula (I)in-line-formulae description="In-line Formulae" end="lead"?R1R2R3CNC   (I)in-line-formulae description="In-line Formulae" end="tail"?and a base represented by the formula (II)in-line-formulae description="In-line Formulae" end="lead"?M(OR4)n  (II)in-line-formulae description="In-line Formulae" end="tail"?as a catalyst is provided. According to the method of the present invention, by telomerization reaction of a conjugated diene compound and an alcohol, ethers can be produced industrially advantageously. (In the above-mentioned formulas, each symbol is as defined in the specification.)
