Suzuki-Miyaura cross-coupling reaction catalyzed by a highly stable Pd(P-Phos)Cl2 complex at room temperature under air

A new Pd(P-Phos)Cl2 complex was synthesized and characterized by 1H NMR, 13C NMR, 31P NMR, and X-ray single crystal structure determination. The complex proved to be a highly stable and efficient catalyst for substrates with a wide range of functional groups in Suzuki-Miyaura cross-coupling reactions under air at room temperature. Low catalyst loadings were employed and turnover number of up to 49000 was obtained.
