Ni(C2H4)3, Ni(cdt), or Ni(cod)2 react with tmeda and acrylic acid methyl ester, methyl vinyl ether, and acrylonitrile in ether to afford (tmeda)Ni(H2C=CHCOOCH3)2 (3, orange-red crystals), (tmeda)Ni(H2C=CHCOCH3)2 (4, red crystals), and (tmeda)Ni(H2C=CHCN)2
Catalytic Syntheses of Polycyclic Compounds Based on Norbornadiene-2,5 in the Presence of Nickel Complexes: I. A Choice of the Model for Cyclic [2π + 2π]-Dimerization of Norbornadiene-2,5

The formation of Ni(0)-norbornadiene-2,5 complexes, which are efficient catalysts for [2π + 2π]-cyclodimerization of norbornadiene-2,5 (NBD), was studied. The analysis of processes occurring during the induction period of the catalytic reaction of NBD and the results of elemental analyses of isolated intermediates suggest that the formation of true catalysts of NBD dimerization occurs in a similar manner if different initial nickel compounds are used. The true catalysts may be mononuclear homoligand nickel complexes with two or three NBD molecules as ligands. These complexes are in equilibrium with each other. The catalytic system formed from bis(η3-allyl)nickel is a convenient model for the ongoing research into the catalytic processes and process optimization.
