An inexpensive and highly stable palladium(II) complex for room temperature Suzuki coupling reactions under ambient atmosphere

A new air- and moisture-stable Pd(II) complex 3, which is a highly efficient catalyst for Suzuki reaction with low Pd-catalyst loading (0.01%), has been synthesized and characterized by single-crystal X-ray crystallography. The corresponding Suzuki coupling products were obtained in satisfactory to excellent yields at room temperature in aqueous media under ambient atmosphere.
