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.
