A subject for the invention is to provide a process of producing a dimeric alcohol in high yield with high selectivity by the Guerbet reaction conducted using an alcohol having 4 or less carbon atoms as a starting material in the presence of a complex including a transition metal and of a base. The invention relates to a process of producing an alcohol which includes dimerizing a starting-material alcohol having 4 or less carbon atoms in an environment having a partial hydrogen pressure of 0.1 MPa or higher.

and palladium increases by over 50 degrees as the natural biteangle increases for the [Pd(diphosphine)(2)](BF(4))(2) complexes. The dihedral angle for the Pd(diphosphine)(2) complexes varies less than 10 degrees for the same range of natural biteangles. Equilibrium reactions of the Pd(diphosphine)(2) complexes with protonated bases to form the corresponding [HPd(diphosphine)(2)](+) complexes were
