Transition metal free thioarylation, selenoarylation and arylation of 2-aminomaleimide, using thiophenols, diaryl diselenides and arylhydrazine hydrochlorides respectively, has been reported in DMSO under aerobic condition in presence of K2CO3 at room temperature. The reaction occurs smoothly without prerequisite N-protection of 2-aminomaleimide. The synthesis of novel, polyfunctionalized maleimides
已经报道了在DMSO中在有氧条件下在室温下在室温下存在K 2 CO 3的情况下分别使用硫酚,二芳基二硒化物和芳基肼盐酸盐的过渡金属游离的硫代芳基化,2-氨基马来酰亚胺的芳基化和芳基化。该反应平稳进行而没有先决条件的2-氨基马来酰亚胺的N-保护。新型,多官能化的马来酰亚胺的合成已通过烯胺的直接C–H活化而实现。Thioarylation和selenoarylation提出要继续经由二硫化物/ diselenides和芳基化已提议将继续经由芳自由基。
