Nitrogen- and phosphorus-coordinated nickel(II) complexes as catalysts for the oligomerization of ethylene
摘要:
Nitrogen- and phosphorus-coordinated nickel(II) complexes 1 and 2 are active precatalysts together with the cocatalyst MAO for the oligomerization of ethylene mainly favoring the production of butenes. The nickel(II) complex 2b reveals a good selectivity at higher ethylene pressure for the production of 1-butene. (C) 2004 Elsevier B.V. All rights reserved.
