摘要
An efficient metal-free Sonogashira coupling protocol catalysed by DABCO is reported, where very good conversions and selectivities to the cross-coupling product were obtained under mild reaction conditions. The reported solvent-, phosphane- and metal-free protocol, that uses a cheap base as catalyst, considerably improves the green credentials of the reaction.
