Nickel-Catalyzed Suzuki–Miyaura Couplings in Green Solvents

Publication Date (Web): July 23, 2013 (Letter)
DOI: 10.1021/ol401727y

The nickel-catalyzed Suzuki–Miyaura coupling of aryl halides and phenol-derived substrates with aryl boronic acids using green solvents, such as 2-Me-THF and tert-amyl alcohol, is reported. This methodology employs the commercially available and air-stable precatalyst, NiCl2(PCy3)2, and gives biaryl products in synthetically useful to excellent yields. Using this protocol, bis(heterocyclic) frameworks can be assembled efficiently.
