Aryl triflate is a type of facile and readily available compounds, which could be used as an alternative substrate for Suzuki cross coupling. In this manuscript, a novel ppm-Pd-Fe/C catalyst has been developed by reduction of palladium acetate and iron trichloride with aqueous hydrazine in situ and supported on activated charcoal. In combined with Sphos, and metal zinc as additives, this catalyst, with 300 ppm palladium loading, could be applied in the Suzuki cross coupling between aryl triflates with aryl neopentylglycolboronates.
