Stille-Carbonylative cross-coupling

A common alteration to the Stille coupling is the incorporation of a group between R1 and R2, serving as an efficient method to form . This process is extremely similar to the initial exploration by Migita and (see History) of coupling organostannane to . However, these moieties are not always readily available and can be difficult to form, especially in the presence of sensitive . Furthermore, controlling their high reactivi
ty can be challenging. The Stille-carbonylative cross-coupling employs the same conditions as the Stille coupling, except with an atmosphere of (CO) being used. The CO can coordinate to the palladium catalyst (9) after initial oxidative addition, followed by into the Pd-R1 bond (10), resulting in subsequent to the ketone (12). The step is normally the .
