SPG sulfinates are also competent in numerous sulfinatebased chemistries. SES sulfinate is compatible Willis' photocatalytic sulfonylation of aniline or Bull's sulfonylation of benzaldehyde (see Supporting information, Table ). SES and oNB-R sulfinate are compatible in Shreedhar's iron catalyzed sulfonylation of alcohols, while PMB-R, oNB-R and SES sulfinates are all compatible with Manolikakes' para-sulfonylation of pyridines using Tf2O (Table ).
