Suzuki–Miyauracoupling: We disclose a new strategy for phenol activation in the first Suzuki–Miyauracoupling of phenol derivatives activated by forming aryl bis(2‐oxo‐3‐oxazolidinyl)phosphines as a highly efficient and broadly applicable methodology for the diverse synthesis of biaryls and heterobiaryls (see scheme). The use of readily available, stable NiCl2/dppp as the catalyst system also provides
