Abstract

Carbonylation reactions serve as powerful tools to construct useful carbonyl compounds with high efficiency and atom economy. Compared with the well-developed carbonylation chemistry for alkenes, the dearomative carbonylation of arenes is largely underexplored, possibly owing to the severe challenge in overcoming resonance stabilization of arene π-systems. Bifunctional coordination to tricarbonylchromium not only offers a reliable strategy to activate inert benzene π-bonds towards dearomatizations but also provides the CO source for the carbonylation process. Herein, we highlight the recent progress in dearomative carbonylations of chromium-bound arenes through either the conventional nucleophile-electrophile addition mode or the newly-developed umpolung-enabled nucleophile-nucleophile addition mode under mild CO-gas-free conditions. Given the great abundance and diversity of arene substrates, we hope this review will attract more attention to this new direction of carbonylation chemistry.
