The use of the Pd(dba)12/dpe catalytic system in allylic alkylation allows sodium dimethyl malonate to react with allylicacetates at room temperature. According to this procedure, a novel synthesis of allylicsubstituted cyclopentadienes is described through the use of cyclopentadienide anion as a nucleophile.
