The Suzuki-Miyaura coupling (SMC) is widely used in C-C bond forming reactions but the dominant mode of transmetalation remains controversial. Here the authors report a mechanistic study of a Pd catalyzed SMC under biphasic conditions where using phase transfer catalysts shifts the dominant mode of transmetalation resulting in rate enhancement.
