This paper reports the first difunctionalization arylation of alkenes. The reaction proceeds through a radical pathway involving the sequential addition of an aromatic radical and an oxime group under photocatalyst/additive- and metal-free conditions. Additionally, TBN functions both as the HAT reagent and as the source of oxime. This method provides mild conditions and simple operation, yielding a wide range of α-arylethanone oximes in moderate to good yields.
