Konishi, Hideyuki published the artcilePd-Catalyzed Selective Synthesis of Cyclic Sulfonamides and Sulfinamides Using K2S2O5 as a Sulfur Dioxide Surrogate, SDS of cas: 500563-90-6, the publication is Organic Letters (2017), 19(7), 1578-1581, database is CAplus and MEDLINE.
A variety of cyclic sulfonamides and sulfinamides could be selectively synthesized under Pd catalysis using haloarenes bearing amino groups and a sulfur dioxide (SO2) surrogate. The amount of base was key in determining the selectivity. Mechanistic studies revealed that sulfinamides were initially formed via an unprecedented formal insertion of sulfur monoxide and were oxidized to sulfonamides in the presence of an iodide ion and DMSO.
