propose a simplecatalyticsystembased on copper iodide for the reaction with bromoalkenes and bromoalkynes, and based on copper dichloride for the coupling with terminal alkynes. The fluorinated chain was varied from perfluorobutyl to monofluoromethyl. The reaction proceeds efficiently when the unsaturated system is substituted by an aryl or alkyl group. In particular, aliphatic terminal alkynes are efficient
photoredox‐initiated 1,2‐difunctionalization of alkene derivatives with N‐chloro S‐fluoroalkyl sulfoximines yielding novel fluoroalkyl sulfoximine scaffolds. The reaction is proposed to proceed through an atom‐transfer radicaladdition (ATRA) mechanism involving the generation of fluorinated nitrogen‐centered sulfoximidoyl radicals.
N-Acylated perfluoroalkylated sulfoximines are synthesized easily from the corresponding free NH-sulfoximines on reaction with acid chlorides. This mild procedure is extended to diacid chlorides for the preparation of dimeric N-bridged sulfoximines and to reactions with chloroformates, carbamoyl chlorides, chlorothionoformates and thiocarbamoyl chlorides as electrophiles.
