We applied a classifier method to predict palladium catalysts for producing non-alternating polyketones via the copolymerization of CO and ethylene; current reported examples are limited to using phosphine sulfonate and diphosphazane monoxide supporting ligands. With this workflow, we were able to discover two new classes of palladium complexes capable of achieving the synthesis of non-alternating polyketones with a lower CO content than known palladium catalysts. Our results show that we doubled the number of known classes of palladium compounds that can catalyze the formation of this type of polymer. We envision that this methodology can be applied to accelerate catalyst discovery when selectivity is an important outcome.
