The direct C2‐functionalization of pyridines through a transition‐metal‐free protocol by using aryne multicomponent coupling is demonstrated. The reaction allowed a broad‐scope synthesis of C2‐substituted pyridine derivatives bearing the −CF3 group in good yields with α,α,α‐trifluoroacetophenones as the third component. Activated keto esters could also be employed as the third component in this formal...
