A mild and operationally convenient formation of synthetically valuable N-sulfonyl iminesfrom a range of aryl aldehydes by reaction with iminoiodinanes (PhINZ) and I2 has been developed. According to mechanistic experiments described within, the reaction is speculated to proceed through an unconventional light-promoted, N-centered radical (NCR) pathway involving a N,N-diiodosulfonamide reactive species

Iron-catalyzed sulfonylimine synthesis under neutral conditions
A convenient FeCl3-catalyzed synthesis of N-sulfonylimines via the condensation of aldehydes with N-sulfonylamides in mild and neutral conditions (in ethanol at room temperature) is reported. This procedure constitutes the first iron-catalyzed synthesis of N-sulfonylimines and is adapted to the condensation of both aromatic and aliphatic aldehydes. (C) 2009 Elsevier Ltd.

Visible-Light, Iodine-Promoted Formation of N-Sulfonyl Imines and N-Alkylsulfonamides from Aldehydes and Hypervalent Iodine Reagents
Alternative synthetic methodology for the direct installation of sulfonamide functionality is a highly desirable goal within the domain of drug discovery and development. The formation of synthetically valuable N-sulfonyl imines from a range of aldehydes, sulfonamides, and PhI(OAc)2 under practical and mild reaction conditions has been developed. According to mechanistic studies described within, the reaction

visible-light-promoted deoxygenative alkylation of imines with alcohols assisted by carbon disulfide and tricyclohexylphosphine. The key to success of this method is the activation of alcohols upon the formation and direct photoexcitation of xanthate anions. This one-pot protocol enables the selective C–O bond homolysis of diverse primary, secondary and tertiaryalcohols to react with a variety of N-sulfonyl and N-aryl
