mono-organothiolation of the C–H bond in ferroceneamide has been developed using aryl/alkyl disulfide substrates. The sequential ferrocene C–H organochalcogenation (chalcogen = S, Se, and Te) has also been established for the synthesis of novel hybrid unsymmetrical arylchalcogenides with the aid of a catalytic amount of Cu(OAc)2 under ambient reaction conditions. The developed protocol results in a broad functional

A copper(I)-catalyzed conjugate addition/enantioselective protonation with selenols and α-substituted α,β-unsaturated thioamides is disclosed, which affords a series of chiral selenides in high to excellent enantioselectivity.
AbstractA metal‐free and efficient visible‐light‐induced spirocyclization of indolyl‐ynones with diselenides at room temperature under air atmosphere to prepare 3‐selenospiroindolenines in moderate to good yields has been developed. The resulting products were tested for in vitro anticancer activity by MTT assay, and compounds 3 c and 3 e showed potent cancer cell‐growth inhibition activities.
