New synthetic approaches to the atom-economical conversion of low-cost feedstocks derived from shale gas, particularly ethylene, to value-added chemicals are attractive to the agrochemical and fine chemical industries. Advances in the use of dicationic, square planar d8 Ni(II), Pd(II), and Pt(II) complexes for the cross-dimerization of ethylene with substituted olefins will be presented. Tightly bound, sterically bulky, neutral pincer ligands impart high catalyst stability and selectivity in these systems. The impact of the identity of the dicationic metal center as well as the steric and electronic properties of the pincer ligand on reactivity and selectivity will be discussed.
