Ruthenium-Catalyzed Decarboxylative Allylation of Nonstabilized Ketone
— The formal [3,3] rearrangement and decarboxylation of allyl β-keto45- 056 Enolates.
esters affords enolates under extremely mild conditions with excellent yields.
Ru(bipy)(C5Me 5)Cl, generated in situ, is found to be the most efficient catalyst for the
reaction. The electron-donating groups on the aryl substituent accelerate the reactions
which are more sluggish with electron-withdrawing substituents. — (BURGER, E. C.;
