The iron complex Bu4N[Fe(CO)(3)(NO)](TBA[Fe]) catalyzes the intermolecular allylation of naphthol derivatives to give the corresponding partially dearomatized allylated chromenones in good to excellent yields. The scope and limitations are reported. An efficient decarboxylative intramolecular C- allylation, starting from allyl naphthyl carbonates, was developed. From a mechanistic point of view, the overall process is the result of a fast O- allylation followed by a sigmatropic rearrangement to the desired product.
