Palladium-catalyzed allylalkynylation of benzynes: a highly efficient route to substituted 1-allyl-2-alkynylbenzenes
Abstract
Benzynes, generated in situ from 2-(trimethylsilyl)aryl triflates and cesium fluoride, undergo allylalkynylation with allylic chlorides and alkynylstannanes in the presence of palladium catalyst to give 1-allyl-2-alkynylbenzenes in good to excellent yields. [reaction: see text]
