A Novel Synthesis of 1,3-Enynylselenides via Cross Coupling of (E)-α-Selanylvinylstannanes with Haloalkynes
摘要:
Conjugated enynes bearing a selanyl group were conveniently obtained under mild conditions via cross coupling of the corresponding vinyltines with 1-haloalkynes in the presence of palladium catalysts.
