New type formation of 1,3-enynes (or internal alkynes) via coupling of organoboranes with alkynylcopper compounds mediated by copper(II)
Chemical Communications Pub Date: 1900-01-01 DOI: 10.1039/A800242H
Abstract
The copper(II)—mediated coupling reaction of alkenyldialkyl- or trialkyl-boranes with alkynylcopper compounds (generated in situ), in the presence of appropriate solvents and a small amount of water, gives (E)-1,3-enynes (or disubstituted alkynes) with various functional groups in reasonable yields.
