After the photoredox autocatalytic nature of the reaction was established,the scope of self-synthesizing BASNs was examined (Figure ). We were delighted to find generally high (up to 92%) yields and the library of structures (photocatalysts) is broad (34 examples), with varying the electronics and positions of the substituents on the aryl sulfonyl group (2a to 2p) and aminoaryl group (2q to 2ad). This suggests the photoredox autocatalytic phase is much more generally applicable than anticipated. Exceptions were present such as 2h and 2o which were afforded in relatively low yields as ortho-substituents on the aryl sulfonyl side promoted a Smiles-Truce rearrangement . Substrates bearing aryl sulfonyls which are too electron poor or with extended conjugation were not well-tolerated as either desulfonylation (1ai to 1ak) or no reaction (1al) was observed. Representative examples (2a, 2b, 2j, 2q, 2w, 2z, 2ae, 2af, 2ag, and 2ah) were accessed on a semi-preparative scale using a commercially available photo-flow reactor without optimization in moderate to high yields (Figure , yields in parenthesis).
