be constructed in only two steps. It complexes Pd(OAc)2 forming a precursor of a very active catalyst useful for Suzuki–Miyaura cross-couplings of functionalized substrates. By a combination of pre-activation, used together with the uncommon solvent EtOAc, the resulting catalyst system is effective at loadings in the ppm (0.1–0.5 mol%) range with highly functionalized reaction partners.
