is reported. Rongalite as a novel precursor of super electron donors was used to initiate a series of electron-catalyzed reactions under mild conditions. These transition-metal-free radical chain reactions enable the efficient formation of C–C, C–S, and C–P bonds through homolytic aromatic substitution or SRN1 reactions. Moreover, the synthesis of antipsychotic drug Quetiapine was performed on gram
报道了一种从芳基卤化物产生芳基的新的实用方法。菱铁矿作为超电子给体的新型前体被用于在温和条件下引发一系列电子催化的反应。这些过渡金属自由基链反应可通过均相芳族取代或S RN 1反应有效地形成C–C,C–S和C–P键。此外,通过所述方法以克为单位进行了抗精神病药物喹硫平的合成。该方案证明了其作为有机合成中有希望的芳构化方法的潜力。
