yields with high regioselectivity from readily available aromatic compounds and aryl/alkyl thiols, even on gramscale. To demonstrate the practicability of this reaction, two bioactive compound skeletons were synthesized in good yields. This method can also be used to late‐stage modification of curcumin.

AbstractAn iodine‐catalyzed sulfenylation of free indoles with sodium sulfinates is described. The reaction selectively afforded 3‐arylthioindoles in good to high yields in anisole under metal‐free conditions. Functional groups such as halogens were well tolerated under the optimized reaction conditions.magnified image
