Abstract:

An effective method for C-5 arylation of 1,4-disubstituted 1,2,3-triazoles and C-5 regioselective arylation of 1-substituted 1,2,3-triazoles via sp2 C–H activation with palladium as a catalyst and diaryliodonium salts as arylating reagents is described. Various electron-rich and electron-deficient substituents attached to triazoles and diaryliodonium salts were tolerable to give the desired products with good isolated yields in 24 hours under air atmosphere.

Abstract:

Direct arylation is an atom-economical alternative to more established procedures such as Stille, Suzuki or Negishi arylation reactions. In comparison with other palladium sources and ligands, the use of palladium pincer complexes as catalysts or pre-catalysts for direct arylation has resulted in improved efficiency, higher reaction yields, and advantageous reaction conditions. In addition to a revision of the literature concerning intra- and intermolecular direct arylation reactions performed in the presence of palladium pincer complexes, the role of these remarkably active catalysts will als

Abstract:

AbstractAryl rings are ubiquitous in the core of numerous natural product and industrially important molecules and thus their facile synthesis is of major interest in the scientific community and industry. Although multiple strategies enable access to these skeletons, metal-catalyzed C–H activation is promising due to its remarkable efficiency. Commercially available organoboron reagents, a prominent arylating partner in the cross-coupling domain, have also been utilized for direct arylation. Organoborons are bench-stable, inexpensive, and readily available coupling partners that promise regio

Abstract:

We report a general, direct C–H arylation of anilide derivatives using reusable palladium or copper oxide on magnetite as heterogeneous precatalysts. Highly selective ortho and meta arylations are achieved using electronically and sterically diverse diaryliodonium salts. Catalytically active soluble species from the heterogeneous precursors were detected by experimental techniques. Preliminary mechanistic investigation suggests different reaction pathways for each of the catalysts.

Abstract:

N-Arylated aliphatic and aromatic amines are important substituents in many biologically active compounds. In the last few years, transition-metal-mediated N-aryl bond formation has become a standard procedure for the introduction of amines into aromatic systems. While N-arylation of simple aromatic halides by simple amines works with many of the described methods in high yield, the reactions may require detailed optimization if applied to the synthesis of complex molecules with additional functional groups, such as natural products or drugs. We discuss and compare in this review the three mai

Abstract:

The use of the congested aryl bromide 2-bromo-1,3-dichlorobenzene as coupling partner allows to modify the regioselectivity of the arylation of 3-substituted thiophene derivatives in favour of carbon C5. The coupling of this aryl bromide with a variety of 3-substituted thiophenes gave in all cases the desired 5-arylation products in moderate to good yields using only 0.5 mol % of a phosphine-free and air-stable palladium catalyst. Then, from these 5-arylthiophenes, a second palladium-catalysed C–H bond functionalization at C2 of the thiophene ring allows the synthesis of 2,5-diarylthiophenes w

Benzylic C–H arylation of azaarylmethanes with aryl sulfides has been developed by using a Pd-NHC catalyst and an amide base.

Moreover, triarylmethane synthesis was accomplished through iterative arylations of 2- or 4-methylpyridine with two different aryl sulfides.

Abstract:

An external oxidant-free, base-free direct C–H arylation of anilides by visible-light mediated metal-free photoredox catalysis in tandem with palladium catalysis is described. The reaction operates at room temperature, without a silver-salt activator and additives, and no generation of copious metal waste.

Abstract:

Allylic arylation of allylic acetates by sodium tetraarylborates in the presence of ppb to ppm (molar) loadings of a palladium NNC-pincer complex catalyst in methanol at 50 °C gave the corresponding arylated products in excellent yields.

Abstract:

A direct arylation to furnish diarylmethanes from benzyl alcohols was realized through Pd(PPh<sub>3</sub>)<sub>4</sub>-catalyzed Suzuki–Miyaura coupling via benzylic C–O activation in the absence of any additives. The arylation is compatible with various functional groups. This development provides an atom- and step-economic way to approach a diarylmethane scaffold under mild and environmentally benign conditions.
