Butadiene from acetylene-ethylene cross-metathesisElectronic supplementary information (ESI) available: Detailed experimental procedures, catalyst screening, solvent screening, influence of catalyst loading, influence of using a butadiene containing feed. See DOI: 10.1039/c5cc00853k
Acetylene to butadiene direct synthesis, via enyne cross-metathesis, is demonstrated with commercial ruthenium carbene catalysts. Using excess of ethylene, yields greater than 50% are obtained. High activity is observed in the first minute of the reaction (TOF > 800 h −1 based on butadiene). Cata...

Zusammenfassung: | Acetylene to butadiene direct synthesis,
via
enyne cross-metathesis, is demonstrated with commercial ruthenium carbene catalysts. Using excess of ethylene, yields greater than 50% are obtained. High activity is observed in the first minute of the reaction (TOF > 800 h
−1
based on butadiene). Catalyst reusability and poisoning are discussed.
Direct synthesis of butadiene from acetylene and ethylene,
via
enyne cross-metathesis, is demonstrated with commercial ruthenium carbene catalysts. |
