Decarboxylative Allylation of Ketone Enolates with Rh, Ir, and Mo

Decarboxylative Allylation of Ketone Enolates with Rh, Ir, and Mo A variety of catalysts were investigated for their ability to impart branched regioselectivity in decarboxylative allylation reactions. While catalysts based on Mo, Rh, and Ir were active catalysts, their regio-selectivities were low and the reactions required an equivalent of base for efficient coupling. Alternatively, a ruthenium-based catalyst was identi-fied that operates under neutral conditions and gives high branched selectivity in decarboxylative allylations.
