Photochemical CO Release from a Bench-Stable, Recyclable Organic Platform: Applications to Carbonylative Cross-Coupling.  Org. Lett.   2025 , ASAP.  Summary figure:   Background:  Carbonylation reactions are   really nice 3 component reactions that usually form ketones. I've posted about one of them previously (https://alwaysbecoupling.blogspot.com/2025/03/palladium-promotes-precise-conversions.html) if you want to see an example. The general idea is you can do migratory addition with a metal carbonyl to form a C-C bond, and then eventually reductively eliminate from the metal acyl complex to form another C-C bond.   Usually, there are two difficulties. First, you have to get the relative rates right, or else you can directly couple your R groups. This is also a common issue with other three-component coupling reactions like dicarbofunctionalizations.  Second, y...
