With our compliments: The 1,3‐dicarbonyl unit has been shown to be a new and useful leaving group for iron‐catalyzed bond cleavage (see scheme). This new strategy can complement the traditional Friedel–Crafts reaction and was applied in the synthesis of indene derivatives.

A highly efficient gold- and silver-catalyzed allylicalkylation of 1,3-dicarbonyl compounds with allylic alcohols has been developed. The reaction was shown to proceed expediently for a wide variety of 1,3-dicarbonyl compounds and allylic alcohols, including 1° and terminal ones, under very mild conditions at room temperature in good to excellent yields (55–96%).
