available N‐aryl conjugated hydrazones with tert‐butyl iodide has been developed. In this reaction, tert‐butyl iodide is used as anhydrous HI source, and the generated HI acts as a Brønsted acid and a reducing agent. This operationally simple method allows access to various indole derivatives. Furthermore, the procedure can be applied to the synthesis of biologicallyactive compounds.

A simple and efficient synthesis of 1(2H)phthalazinone derivatives was achieved via a reaction of phthalaldehydicacid and various phenyl hydrazines in CHCI3 in the presence of a catalytic amount of different heteropolyacids (HPAs) in very good yields.

We describe a new functional group metathesis between aryl nitriles and aryl thioethers. The catalytic system nickel/dcype is essential to achieve this fully reversible transformation in good to excellent yields. Furthermore, the cyanide- and thiol-free reaction shows high functional group tolerance and great efficiency for the late-stage derivatization of commercial molecules. Finally, synthetic applications

Transition metal free thioarylation, selenoarylation and arylation of 2-aminomaleimide, using thiophenols, diaryldiselenides 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。
