The Suzuki–Miyaura (SM) coupling is one of the most used and versatile reactions in organic synthesis. However, the use of precious metal-based catalysts – such as Pd – represents a limitation, especially when the reaction needs to be performed on a large scale. Recently, the group of Professor Mark Stradiotto (Dalhousie University, Halifax, Canada) reported an interesting SM-type strategy for the synthesis of unsymmetrical biheteroaryls based on the use of an air-stable nickel pre-catalyst.
