strategy employing N-thiosuccinimides and (EtO)2P(O)SH has been developed to synthesize unsymmetrical organophosphorus disulfides (P(O)–S–S motif). A pronucleophile (EtO)2P(O)SH, Brønsted acid and phosphorothioate nucleophile, converts N-thiosuccinimides into unsymmetrical phosphorus disulfides. This protocol achieves catalyst- and additive-free reaction conditions, uses a renewable solvent (EtOH), and avoids
采用N-硫代琥珀酰亚胺和(EtO) 2P (O)SH的硫介导的umpolung策略已被开发用于合成不对称有机磷二硫化物(P(O)–S–S基序)。亲核试剂 (EtO) 2 P(O)SH、布朗斯台德酸和硫代磷酸酯亲核试剂,可将N-硫代琥珀酰亚胺转化为不对称的二硫化磷。该方案实现了无催化剂和无添加剂的反应条件,使用可再生溶剂(EtOH),并避免使用刺激性试剂。
