Abstract

Abstract Room-temperature Suzuki–Miyaura aryl–aryl cross-coupling reactions have been achieved in high yields by using an easily accessible, air-stable Ni II–(σ-aryl) complex as precatalyst without either the pretreatment of organometallic reagents or the presence of external reductants. The Ni II complex, in conjunction with monophosphane ligands such as PCy 3· HBF 4 or PPh 3, allowed the efficient cross-coupling of aryl sulfonates (OTs, OMs) ...
