Get selective! Enantioselective allylation of ketimines derived from isatins by using chiral 1,3‐bis(imidazolin‐2‐yl)benzene (Phebim)–PdII complexes afforded products with good enantioselectivity (see scheme). The reaction was applied to a wide variety of ketimines. The obtained product can be converted to homoallylic amines and a spirocyclic amine without the loss of enantiopurity.

Photoreaction between dicyanobenzenes and a hypervalent allylsilicon reagent using 2,3-dihydroxynaphthalene as a ligand on silicon efficiently proceeded to afford allyl-substituted benzonitriles in moderate to good yields. The present photoreaction was found to occur based on the excitation of the hypervalent allylsilicon reagent.

Palladium-catalyzed remote sp2–sp3 coupling reaction of chloromethylarenes with allyltrimethoxysilane is described in this work. The allylation reaction regioselectively occurred on the para-positions of 1-(chloromethyl)naphthalenes and benzyl chlorides to form new C(sp2)–C(sp3) bonds. The reaction proceeds smoothly under mild conditions to produce allyl arenes in moderate to excellent yields.
