Transition-Metal-Catalyzed Benzylation of Arenes and Heteroarenes

Friedel–Crafts‐type benzylation of various aromatic and heteroaromatic compounds with benzylic acetates, alcohols, and carbonates was promoted under mild reaction conditions by a series of Rh, Ir, Pd, and Pt catalysts (see scheme; R1=H, Me; R2=H, Cl, MeO; R3=H, Ac, CO2Me). The desired products were...

Zusammenfassung:	Friedel–Crafts‐type benzylation of various aromatic and heteroaromatic compounds with benzylic acetates, alcohols, and carbonates was promoted under mild reaction conditions by a series of Rh, Ir, Pd, and Pt catalysts (see scheme; R1=H, Me; R2=H, Cl, MeO; R3=H, Ac, CO2Me). The desired products were obtained in high yields and with high selectivities.
