Esters (mixed anhydrides) derived from aliphatic or alicyclic carboxylic acids (RCO2H) and thiohydroxamic acids or undergo a thermally or photochemically induced radical chain reaction to give sulphides with loss of carbon dioxide. On irradiation at low-temperature however, the chain reaction is essentially supressed. Under these conditions moderate to good yields of dimers R-R are obtained from primary
衍生自脂肪族或脂环族羧酸(RCO 2 H)和硫代异羟肟酸的酯(混合酸酐),或经过热或光化学诱导的自由基链反应,生成硫化物,并减少二氧化碳的损失。然而,在低温下照射时,链反应基本上被抑制。在这些条件下,从伯酸获得中等至良好产率的二聚体RR。讨论了这些观察结果的机理和综合意义。
