安息香酸フェニルに依るベンゾイル化 (第2報)

芳香族ズルフオンアミドのベンゾイル化

抄録

1) A new method of benzoylation in which the N-benzoylated aromatic sulfonamides are obtained by the fusion of a mixture of phenyl benzoate, aromatic sulfonamide and anhydrous alkali carbonates, or of phenyl benzoate and alkali salts of aromatic sulfonamides, was examined.
2) By this method of benzoylation, p-amino- and p-hydroxybenzenesulfonamide give only their N¹-benzoylated products in good yields.
3) By extensive application, this method can be used as a novel acylation of aromatic sulfonamides by the use of phenyl esters of aliphatic, aromatic and heterocyclic carboxylic acids.
