More powerful sulfonylating reagent than the sulfonyl chloride, also avoiding possible displacement of sulfonate by halide. This is particularly useful in the sulfonylation of hindered alcohols and sugars: J. Chem. Soc., 1225 (1953)./n
Anions of ß-ketoesters react with p-toluenesulfonic anhydride to give enol tosylates in good yield; tosyl chloride gives poor results (ca 20%): Synth. Commun., 20, 881 (1990)./n
Has been used in combination with Paraformaldehyde, A11313 in the generation of monomeric formaldehyde: Synlett, 704 (1990)./n
