The influence of four parameters (temperature, scavenging time, amount of scavenger, and concentration of palladium in the solution) on the efficiency of Pd removal from a cross-coupling reaction, using a commercially available Pd scavenger, SPM32, was studied. The DoE-based method employed yielded more information than is readily attainable from standard adsorption isotherms and kinetics experiments. The optimal regime of scavenging was identified; intuitive and nonintuitive effects of temperature, scavenging time, and scavenger amounts were highlighted; and a mathematical model quantifying predicted Pd removal from the synthetic intermediate was built.
