Bis(μ-iodo)bis((−)-sparteine)dicopper(I) catalyzed Sonogashira-type reaction under palladium and phosphine-free conditions

An efficient and inexpensive protocol for the Sonogashira-type cross coupling reactions of phenylacetylenes with a variety of haloarenes including activated aryl chlorides employing the structurally well-characterized bis(μ-iodo)bis((−)-sparteine)dicopper(I) catalyst is described.
