desaturation of N‐protected lactams, ketones, and lactones to their conjugated α,β‐unsaturated counterparts is reported. The reaction operates under mildly acidic conditions at room temperature or 50 °C. It is scalable and tolerates a wide range of functional groups. The complementary reactivity to the palladium‐catalyzed desaturation is demonstrated in the efficient conversion of iodide, bromide, and sulfur‐containing
据报道,一般的铂催化的N保护的内酰胺,酮和内酯与其共轭的α,β-不饱和对应物的去饱和反应。该反应在室温或50°C的弱酸性条件下进行。它具有可扩展性,并可以容纳各种功能组。碘化物,溴化物和含硫底物的有效转化证明了与钯催化的去饱和反应的互补反应性。
