Utilization of High-Throughput Experimentation (HTE) and ChemBeads Toward the Development of an Aryl Bromide and Benzyl Bromide Photoredox Cross-Electrophile Coupling

Abstract

The discussion herein describes a metallaphotoredox reaction that allows for efficient exploration of benzyl structure−activity relationships in medicinal chemistry. The use of HTE (high-throughput experimentation) and ChemBeads allows for rapid reaction optimization. The formation of di(hetero)arylmethanes via cross-electrophile coupling between aryl bromides and benzyl bromides provides access to diverse chemical space. The breadth of the substrate scope will be discussed, along with the utilization of batch photochemistry for the preparation of this di(hetero)arylmethane motif on a larger scale.
