ABSTRACT:
A process for preparing derivatives of isoprene dimers, which are useful as materials for producing perfumes, pharmaceuticals and industrial chemicals, comprising catalytically reacting isoprene with an active methyl-containing compound, such as methacrylonitrile, using bis-.pi.-allyl nickel or bis-cyclooctadiene nickel as a catalyst and triphenyl phosphine, triphenyl phosphite, tributyl arsenic or tricyclohexyl phosphine as a ligand and a tertiaryamine compound as a solvent.
