A regioselective Rh(III)-catalyzed C-H bond naphthylation and cascade directing group (DG) transformation has been realized with aryl imidates oxa bicyclic alkenes. Diverse naphthalene-substituted aromatic esters were synthesized fruitfully. The DG into ester endows the strategy chances of further functionalization derivatization. Preliminary mechanistic studies demonstrate that carbonyl oxygen possibly originates from corresponding alkene.

Abstract The mechanisms of α‐C cross coupling π‐bonds catalyzed by iron complexes have been investigated using density functional theory (DFT) calculations with the B3LYP‐D3BJ in solvation model (SMD) (dichloromethane). results show that overall catalytic cycle includes deprotonation α‐position alkynes, electrophilic functionalization, protonation and BF 3 departure, alkynes exchange, catalyst regeneration. step is rate‐determining whole where energy barrier Δ G sol dichloromethane solution 11.6 kcal/mol. Our also product a racemic form, which keeps consistent experimental results.
