New thio- and seleno-hydroxamic acids have been synthesized from various 4,4-disubstituted thiazolidine-2,5-dithiones. Their corresponding O-acyl derivatives rearrange photochemically, with visible light, in an identical manner to the acyl derivatives of N-hydroxy-2-thiopyridone. A wide range of half-lives was observed.
已经从各种4,4-二取代的噻唑烷-2,5-二硫酮合成了新的硫代和硒代异羟肟酸。它们相应的O-酰基衍生物以与N-羟基-2-硫代吡啶酮的酰基衍生物相同的方式在可见光下进行光化学重排。观察到宽范围的半衰期。
