Herein, sulfinyl chlorides and styrenes have been exploited to afford either β-hydroxy-phenylethyl sulfides catalyzed by homogenous ZnCl2, or β-chloro-phenylethyl sulfones mediated by heterogeneous CuO nanoparticles (NPs). The key to achieve such a divergent synthetic strategy is the controlled disproportionation process of sulfoxide-onium ions, induced by different metal complexes. Owing to the mild
在此,亚磺酰氯和苯乙烯已被用于提供由均相 ZnCl 2催化的 β-羟基-苯乙基硫化物,或由异质 CuO 纳米颗粒 (NP) 介导的 β-氯-苯乙基砜。实现这种不同合成策略的关键是由不同金属配合物诱导的亚砜-鎓离子的受控歧化过程。由于条件温和,两种方案都可以容忍各种官能团和杂环。机理研究揭示了亚砜离子在两种反应途径中的关键作用,并表明金属控制的歧化反应决定了产物中硫的氧化态。
