Abstract

Aryl alkynes are important synthetic precursors and subunits for a range of pharmaceutically attractive and valued materials science organic compounds.[1] One of the most straightforward and versatile protocols for the construction of Csp2ÀCsp bond is the palladium-catalyzed cross-coupling of aryl halides/sulfonates and terminal alkynes, namely, Sonogashira coupling.[2] This methodology features a modular approach to assemble an ...
