Direct Benzylic Alkylation via Ni-Catalyzed Selective Benzylic sp3 C−O Activation
摘要:
This article demonstrates the first cross coupling of benzyl ether with Grignard reagents via Ni-catalyzed benzylic sp(3) C-O activation with high efficiency and excellent chemoselectivity. Benzylic sp(3) C-O and aryl sp(2) C-O were differentiated, controlled by ligands.

Aryl carbonates work as electrophilic substrates for the Suzuki–Miyaura reaction in the presence of the nickel catalyst, which is generated from [Ni(cod)2] and ferrocenyl bisphosphine, DCyPF. The nickel catalyst allowed the cross-coupling reaction of arylboronic acids with non-benzo-fused aryl carbonates as well as naphthyl substrates.
