摘要：

5,5-Diphenylhydantoin (1) by heating with chlorosulfonic acid gave a bis-sulfonyl chloride (2) in which the orientation of sulfonation is apparently meta/para. The chloride (2) was converted into 8 sulfonamides (3-10). Barbituric acid has been condensed with aromatic aldehydes to yield 18 5-arylidene derivatives (11-28). The reaction of chlorosulfonic acid with 5-benzylidenebarbituric acid (H) is discussed together with the subsequent reaction of the sulfonyl chloride with amines. The chlorosulfonation of other arylidenebarbituric acids (12-14, 22, 23, 26 and 28) has also been examined.
