摘要：

The four isomeric bromoquinolizium bromides reacted with aryl- and heteroarylacetylenes under Sonogashira conditions. The reactions proceed with moderate-to-high yields to afford aryl- and heteroarylethynyl quinolizium cations. This is the first reported example of the Sonogashira reaction on heteroaromatic cations, and it allowed easy access to potential pi-donor pi-acceptor systems bearing cationic units.
