Pd/C-mediated allylic substitution in water is described as an interesting alternative to classical homogeneous conditions. The reaction applied to allylic acetates showed a wide range of compatibility with various nitrogen, sulfur, oxygen, and carbon nucleophiles. Notably, the method features inexpensive reagents and a nontoxic solvent. Moreover, measurement of the palladium content in water by ICP-MS
水中Pd / C介导的烯丙基取代被描述为经典均质条件的一种有趣替代方法。应用于烯丙基乙酸酯的反应显示出与各种氮,硫,氧和碳亲核试剂的广泛相容性。值得注意的是,该方法具有廉价的试剂和无毒的溶剂的特点。此外,通过ICP-MS测量水中的钯含量显示出低的钯污染(4 ppm),与均匀条件相比,该方法对环境更安全。还公开了Pd / C介导的烯丙基取代的第一个不对称实例。
