An iron catalyzed reaction for the selective transformation of thiols (‐SH) to sulfinamides (‐SONH2) by a direct transfer of ‐O and free ‐NH2 groups has been developed. The reaction operates undermildconditions using a bench stable hydroxylamine derived reagent, exhibits broad functional group tolerance, is scalable and proceeds without the use of any precious metal catalyst or additional oxidant

A copper-catalyzed sulfinyl cross-coupling reaction of sulfinamides with aldehyde-derived N-tosylhydrazones is described. This approach enables facile access for the construction of structurally diverse sulfoxides via novel and efficient S–N/S–Cbond interconversions, features broad substrate scope, and accommodates various functional groups as well as pharmacophores. Moreover, the given sulfinyl cross-coupling
