Palladium-catalyzed amination of chloromethylnaphthalene and chloromethylanthracene derivatives to produce naphthylamines and anthrylamines in satisfactory to good yields has been developed. The unprecedented amination reactions proceeded smoothly under mild conditions in the presence of Pd(PPh3)(4) as a catalyst.

An efficient method has been developed for the Pd(0)-catalyzed benzylation of indoles, which occurred with exclusive regioselectivity. When this reaction was performed in the presence of Pd(PPh3)(4), it provided access to a broad range of substituted indoles bearing diarylmethanes at their 3-position in 90%-99% yields under mild conditions.

palladium-catalyzed reaction of 1-(chloromethyl)naphthalenes 1 with (hetero)arylacetonitriles 2 gives either para- or ortho-acylated naphthalenes (3 or 4) in good to high yields. The regioselectivity can be controlled by the ligand of a palladium catalyst. A sterically bulky ligand, tBuPPh2, affords para-acylated products 3, whereas a sterically less bulky ligand, Me2PPh, provides ortho-acylated products 4. Further
