摘要：

The ruthenium(II)-allenylidene salt [(p-cymene)(PCy3)-ClRu=C=C=CPh2]PF6 acts as an olefin metathesis catalyst precursor for the yne-ene transformation of the mixed propargylic allyl ethers HC=C-CR2OCH2CH=CH2 into 3-vinyl-2,5-dihydrofurans; initial photochemical irradiation efficiently promotes the catalytic activity.
