A hydroquinone based palladium catalyst for room temperature nitro reduction in water

A hydroquinone based palladium complex [Pd(H2L)(Cl)(2)] (1), acts as an efficient room temperature catalyst for reduction of nitroarenes in water as solvent. 1 also acts as a tandem catalyst for Suzuki-Miyaura cross coupling in ethanol followed by reduction of nitroarenes in one pot with a loading of 0.25 mol% catalyst.
