Abstract
C3-N1' bisindoles are unique structures, and the construction of these structures has drawn much attention. However, their synthesis still presents significant challenges that limit the functional group compatibility. This minireview summarizes the recent progress in the methodology for constructing C3-N1' bisindoles. There are two approaches for access to C3-N1' bisindoles: (1) direct approaches including reverse polarity techniques. (2) Stepwise approaches using designed and prefunctionalized substrates enable further functionalization by additional reactions to facilitate access to the target products. I believe that this review will allow its readers to develop novel approaches for the synthesis of C3-N1' bisindoles.

Abstract
The organic superbase catalyst t-Bu-P4 achieves nucleophilic aromatic substitution of methoxyarenes with alkanenitrile pronucleophiles. A variety of functional groups [cyano, nitro, (non)enolizable ketone, chloride, and amide moieties] are allowed on methoxyarenes. Moreover, an array of alkanenitriles with/without an aryl moiety at the nitrile α-position can be employed. The system also features no requirement of a stoichiometric base, MeOH (not salt waste) formation as a byproduct, and the production of congested quaternary carbon centers.

Abstract
The direct cyanomethylation of indoles at the 2- or 3-position was achieved via photoredox catalysis. The versatile nitrile synthon is introduced as a radical generated from bromoacetonitrile, a photocatalyst, and blue LED as a light source. The mechanism of the reaction is explored by determination of the Stern-Volmer quenching constants. By combining photophysical data and mass spectrometry to follow the catalyst decomposition, the catalyst ligands were tuned to enable synthetically useful yields of radical coupling products. A range of indole substrates with alkyl, aryl, halogen, ester, and ether functional groups participate in the reaction, affording products in 16-90% yields. The reaction allows the rapid construction of synthetically useful cyanomethylindoles, products that otherwise require several synthetic steps.

Abstract
An indole core bearing a functional group on the C2 position is often found as a key structure in biologically active natural products and pharmaceuticals. Here, we report direct C2-functionalization of indoles triggered by the formation of an iminium species generated from indole and a sulfonium reagent. The reaction proceeded under very mild conditions to give the corresponding C2-substituted indole derivatives in good to high yields.

Abstract
The role of the solvent and the influence of dynamics on the kinetics and mechanism of the SNAr reaction of several halonitrobenzenes in liquid ammonia, using both static calculations and dynamic ab initio molecular dynamics simulations, are investigated. A combination of metadynamics and committor analysis methods reveals how this reaction can change from a concerted, one-step mechanism in gas phase to a stepwise pathway, involving a metastable Meisenheimer complex, in liquid ammonia. This clearly establishes, among others, the important role of the solvent and highlights the fact that accurately treating solvation is of crucial importance to correctly unravel the reaction mechanism. It is indeed shown that H-bond formation of the reacting NH3 with the solvent drastically reduces the barrier of NH3 addition. The halide elimination step, however, is greatly facilitated by proton transfer from the reacting NH3 to the solvent. Furthermore, the free energy surface strongly depends on the halide substituent and the number of electron-withdrawing nitro substituents.

We report palladium-catalyzed synthesis of heteroarenes dyads using heteroarylsulfonyl chlorides as coupling partners. The C–H bond functionalizations occurred at α-position with pyrroles and furans, while at β-position with thiophenes.

Abstract
The scope and limitations of a Suzuki reaction between 2-azidoarylboronic acid pinacolate esters and vinyl triflates are reported. This cross-coupling reaction enables the regioselective synthesis of indoles after a subsequent Rh(II)2-catalyzed sp(2)-C-H bond amination reaction.
