ABSTRACT:
A process for preparing 1,7-octadiene by hydrodimerizing butadiene which comprises reacting the butadiene in the presence of formic acid or a salt thereof, optionally a solvent and a catalyst comprising palladium complexed with a tertiary phosphinite or phosphonite. More active catalysts are obtained with phosphinites and phosphonites than with phosphines or phosphites.
