We find a Cu(II)-(L-CF3)2 complex (L-CF3 = 2,2,2-trifluoro-N-[2-(pyridin-2-yl)propan-2-yl]acetamide) with a distorted seesaw geometry. It has the shortest crystallographic CF···Cu distances yet reported, to the best of our knowledge (?), for which computational and experimental data indicate a secondary bonding interaction. A comparison with a CCl3 version and one without ligand backbone gem-dimethyl groups suggests a steric origin for the distorted geometry, resulting from the specific ligand interactions.

Selective functionalization at the meta position of arenes remains a significant challenge. In this work, we demonstrate that a single anionic bipyridine ligand bearing a remote sulfonate group enables selective iridium-catalyzed borylation of a range of common amine-containing aromatic molecules at the arene meta position. We propose that this selectivity is the result of a key hydrogen bonding interaction between the substrate and catalyst. The scope of this meta-selective borylation is demonstrated on amides derived from benzylamines, phenethylamines and phenylpropylamines; amine-containing building blocks of great utility in many applications.

We report a novel and efficient approach to the synthesis of imidazo[1,5-a]pyridine-1-carboxylic acids. By using the reaction of 2-(aminomethyl)pyridine with acyl chlorides followed by one-pot treatment with trifluoroacetic anhydride, 2,2,2-trifluoro-1-im
