describes the efficacy of P,N-type benzimidazolyl phosphineligands, which can be easily synthesized from commercially available and inexpensive starting materials. The application of this ligand array in palladium-catalyzed Suzuki–Miyaura couplingreaction of aryl chlorides with potassium aryltrifluoroborates is described. The air stable benzimidazolyl phosphines in combination with a palladium metal precursor
Abstract The polystyrene-supported Pd(II) N , N -dimethylethylenediamine complex was prepared and characterized by various techniques, including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), atomic absorption spectroscopy (AAS), and thermal analysis (TG-DTA). This heterogeneous Pd(II) catalyst works efficiently for the Suzuki–Miyaura
