ABSTRACT:
The liquid phase dimerization of diolefins is effected by maintaining the diolefins in solution in an inert solvent in contact with a catalyst which is the reaction product of a transition metal carbonyl and a compound which is a transition metal halide or pseudo halide coordinated with groups capable of furnishing three electrons. The dimerization of butadiene to vinyl-4-cyclohexene and cyclooctadiene and the dimerization of C.sub.4 cracked fractions into vinyl-4-cyclohexene are preferred reactions.
