All the results obtained during this study confirm that Sc(OTf)3 possesses noteworthy photocatalytic activity. Hence, we introduce a new aerobic oxidation approach for benzylic substrates with Sc(OTf)3 as the sole photocatalyst. This system revealed considerable efficiency with a wide range of benzylic substrates, including alcohols, toluene derivatives, and methylenecontaining substrates. A straightforward Sc(OTf)3based photocatalytic approach for the oxidative cyanation of arenes under aerobic conditions was also developed as an example of direct aromatic C-H derivatization resulting in C-C bond formation. The photooxidative cyanation method, despite some limitations (e.g. the cyanation of electron-poor substrates), demonstrated an interesting efficiency with a notable regioselectivity across the tested scope of arenes.
