A new ruthenium-catalyzed cleavage of a carbon-carbon triple bond: efficient transformation of ethynyl alcohol into alkene and carbon monoxide.
We report a new and efficient ruthenium-catalyzed reaction that transforms ethynyl alcohol into alkene and carbon monoxide. The most efficient catalysts are TpRu(PPh3)(CH3CN)2PF6 (10 mol %) and lithium triflate (20 mol %). The mechanism of this reaction was elucidated using an isotope-labeling experiment.
