Abstract

A general efficient one-pot synthesis of S-perfluoroalkylated NH-sulfoximines from sulfides has been developed using phenyliodine diacetate (PIDA) and ammonium carbamate. Remarkable rate enhancement with trifluoroethanol was observed, presumably due to H-bonding effects. These mild and metal-free conditions are compatible with -CH <subscript>2</subscript> F, -CFCl <subscript>2</subscript> , -CF <subscript>2</subscript> H, -CF <subscript>2</subscript> Br, -C <subscript>4</subscript> F <subscript>9</subscript> , and -CF <subscript>3</subscript> groups, in both the alkyl- and aryl series. Based on a <superscript>19</superscript> F NMR analysis, a λ <superscript>6</superscript> -acetoxysulfanenitrile intermediate was proposed.<br /> (© 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)
