ABSTRACT:
An ethylene dimerization process is provided wherein ethylene is contacted with an organonickel (0) compound and a phosphine compound in a fluorinated alcohol solvent to produce a precursor reaction mixture, followed by contacting ethylene with the precursor reaction mixture and a fluorinated organoacid to produce a product reaction mixture comprising a C.sub.4 fraction of predominantly 2-butenes.
