Mechanistically the CO insertion is regarded as 1,2-alkyl migration to the cis-bound CO (migratory insertion).

The migration is reversible and an important step in carbonylation. SO2, isonitriles and carbenes are other species that undergo α,α-insertion.

A protocol has been developed for conducting the palladium-catalyzed reductive carbonylation of aryl iodides and bromides using 9-methylfluorenecarbonyl chloride (COgen) as a source of externally delivered carbon monoxide in a sealed two-chamber system (COware), and potassium formate as the in situ hydride source.

A palladium-catalyzed oxidative borylation reaction of conjugated enynones is developed. This reaction represents a new method for the synthesis of furyl-substituted alkenylboronates.

The reaction works well with a series of conjugated enynones. Boryl migratory insertion of the palladium carbene intermediate. Palladium-catalyzed cross-coupling reactions between benzyl, aryl, or allyl bromides and conjugated ene–yne–ketones lead to the formation of 2-alkenyl-substituted furans.

This novel coupling reaction involves oxidative addition, alkyne activation–cyclization, palladium carbene migratory insertion, β-hydride elimination, and catalyst regeneration.
