Tungsten imido catalysts for selective ethylene dimerisation

Abstract

A tungsten imido complex W(NDipp)Me3Cl (Dipp = 2,6-iPr-C6H3) is active for the selective dimerisation of ethylene to yield 1-butene under mild conditions. Immobilisation and activation of W(NDipp)Cl4(THF) on layered double hydroxides, silica or polymethylaluminoxane yields active solid state catalysts for the selective dimerisation of ethylene. The polymethylaluminoxane-based catalyst displays a turnover frequency (4.0 molC2H4 molW−1 h−1) almost 7 times that of the homogeneous catalyst.
