Facile synthesis of multisubstituted buta-1,3-dienes via Suzuki–Miyaura and Kumada cross-coupling strategy of 2,4-diiodo-buta-1-enes with arylboronic acids and Grignard reagents
An unprecedented single-step synthesis of enyne derivatives through Pd-catalyzed arylalkynylation of aryl iodides, Internal alkynes, and alkynylsilanes is described.
