An efficient and mild acyl-alkylation of arynes is described. The method is used to synthesize medium-sized carbocycles by the ring-expansion of cyclic beta-ketoesters.

Lead(IV) tetracarboxylates, prepared from achiral and chiral carboxylic acids, have been shown to undergo metal—metal exchange with phenylboronic acid, and the phenyllead(IV) carboxylates thus generated in situ can be used for Pinhey phenylation reactions. Although the yields of these reactions are generally moderate to good, only low levels of asymmetric induction at best were observed. Possible reasons
