Abstract

A carbon–carbon triple bond is a highly valuable and versatile functional group in many natural products, bioactive compounds,[1] and organic materials.[2] Alkynylstannanes, which have high stability, reactivity, and functional group tolerance, are important reagents for introducing an alkynyl moiety into organic molecules.[3] In particular, the Migita–Kosugi– Stille coupling using alkynylstannanes is widely used for the construction of C (sp) ÀC ( ...
