PURPOSE: To obtain an unsaturated alcohol which is a hydrated even number oligomer of a conjugated alkadiene useful as a raw material for cosmetics, etc., in high yield and selectivity by reacting the alkadiene with water in the presence of carbon dioxide using a pd compound and a specific phosphorus compound as catalysts. CONSTITUTION: This method for producing (E) an unsaturated alcohol having a skeleton obtained by polymerization of a conjugated alkadiene (e.g. 6- vinyl-2,8,13-tetradecatrien-1-ol) is to react (C) a conjugated alkadiene with (D) water in the presence of (B) carbon dioxide using (A) a pd compound and a phosphorus compound having one or more trivalent phosphorus-oxygen single bonds [e.g. a compound of formula I [A<1> is a (substituted)aryl or a (substituted) alkyl; A<2> and A<3> are each a (substituted)arylene; Q is O, S, CO, etc.; (x) and (y) are each 0 or1] or a compound of formula II[A<4> is A<1> ; A<5> and A<6> are each a (substituted)aryl] as catalysts. |
