Carbonyl compounds synthesis, palladium catalysis

The reactions described in this section are not unique to ruthenium catalysis. These transformations can also be achieved using a palladium or a nickel catalyst. Since carbonylative cyclizations leading to cyclic carbonyl compounds are useful transformations in organic synthesis, these reactions are included in this section.

Notably, the catalyst system is currently used on multi-1,000 kg-scale. The efficiency and easy handling properties (stable to air and moisture) make this the first industrial palladium-catalyzed reductive carbonylation of aryl halides. At this point it is important to note that applied homogeneous catalysis benefits significantly from advancements in the area of organometallic chemistry. Hence, the mechanistic understanding of elementary steps and the synthesis of new organometallic compounds provide a valuable source for inspiration for new catalysts.
