A method for producing octadienols, which comprises reacting 1,3-butadiene with water in the presence of a palladium compound, a phosphine compound and carbon dioxide, wherein a compound of the formula (I): ##STR1## wherein each of R.sup.1, R.sup.5 and R.sup.9 which may be the same or different, is a hydrocarbon group, and each of R.sup.2, R.sup.3, R.sup.4, R.sup.6, R.sup.7, R.sup.8, R.sup.10, R.sup.11 and R.sup.12 which may be the same or different, is hydrogen or a substituent, provided that at least one of them is an electron donative substituent, is used as the phosphine compound.

Method for producing octadienols

An improving method for producing alkadienols by reaction of conjugated alkadiene and water in the presence of carbon dioxide and a catalyst composed of a palladium compound and phosphine (or phosphite), wherein the by-products having high boiling point and the palladium catalyst are efficiently separated from the reaction product for re-use without impairing their effectiveness as the catalyst.
