    Abstract: A method for preparing 1,6-octadiene by reacting 1,3-butadiene with formic acid in the presence of a platinum(II) catalyst and a polymeric tertiary amine catalyst is described. The combination of a platinum(II) catalyst such as platinum acetylacetonate with a polymeric tertiary amine promoter such as AMBERLYST.RTM. A21 macroreticular ion-exchange resin gives a high selectivity to 1,6-octadiene as opposed to the 1,7-octadiene form. A reaction temperature between 50.degree. and 150.degree. C. is preferred, and carbon dioxide and a solvent may also be employed.
