摘要

The Friedel–Crafts alkylation of aromatic compounds with alkenes is one of the fundamental methods for incorporating carbon skeletons into aromatic systems and, thus, has been extensively studied and is well established.[1] In contrast, the corresponding alkenylation process with alkynes still remains to be solved. One major drawback from the direct Friedel– Crafts alkenylation of arenes is alkyne polymerization, which results in the formation of a ...
