Three new versions of the Burgess reagent were synthesized and their thermal stability investigated by NMR. The new reagents exhibited improved reactivity toward epoxides, diols, and vinyl oxiranes as compared with the original version.

AbstractSulfoxides can directly be converted into N‐cyanosulfilimines using a new Burgess‐type reagent. By applying this strategy with a related reagent variant, synthetically valuable NH‐sulfoximines have been prepared from sulfoxides via N‐protected sulfilimines. The practical three‐step reaction sequence is generally high yielding and applicable to a wide range of substrates. The sulfoxide‐to‐sulfilimine conversion can also be performed under solvent‐reduced conditions in a ball mill.magnified image
