Direct Transformation of Ethylene into Propylene Catalyzed by a Tungsten Hydride Supported on Alumina: Trifunctional Single‐Site Catalysis

Abstract

A trifunctional single-site catalyst: Ethylene is selectively transformed into propylene in a continuous-flow reactor in the presence of the supported tungsten hydride W(H)3/Al2O3. Since the catalyst is also active for olefin metathesis, the reaction is likely to proceed at a “trifunctional catalytic site” by ethylene dimerization, butene isomerization, and cross-metathesis of ethylene with 2-butenes (see picture).
