Building upon the established optimal conditions for the photocatalytic arylation of Dha 2, both in batch and flow (Table and), we sought to evaluate the versatility and scope of our method. Hereto, we applied various arylthianthrenium salts 4 to the established protocol, as delineated in Scheme 1. Scaling up our model reaction using arylthiantrenium salt 1 and Dha-derivative 2 via flow technology was successful, achieving a 71% isolated yield at a 1.0 mmol scale under our standard conditions.
