Arenes containing conformationally flexible long alkyl chains have been successfully functionalized at the meta-position. Good to excellent meta selectivity is achieved for systems with up to 20 atoms between the target C-H bond and the coordinating heteroatom of the directing group. The palladium-catalyzed functionalization reactions include alkylation, cyanation, olefination, and acetoxylation. The meta selectivity is exclusively governed by the design of flexible pyrimidine-based scaffolds.
