Two Directing Groups Used for Metal Catalysed -C-H Functionalisation Only Effect Electrophilic C-H Borylation.

Two templates used in -directed C-H functionalisation under metal catalysis do not direct -C-H borylation under electrophilic borylation conditions. Using BCl only Lewis adduct formation with Lewis basic sites in the template is observed. While combining BBr and the template containing an amide linker only led to amide directed C-H borylation, with no pyridyl directed borylation.
