Addition Reaction of Immonium Benzotriazolates To Acetylenic Esters

1-Dialkylaminomethylbenzotriazoles react with ethyl propiolate and dimethyl acetylenedicarboxylate by addition of the benzotriazole anion followed by the immonium cation.The benzotriazolyl group in the products undergoes facile nucleophilic displacement.

Synthesis of pyrazole-carboxamides and pyrazole-carboxylic acids derivatives: Simple methods to access powerful building blocks

Hybrid systems containing pyrazole moiety show a wide spectrum of biological activities. To access novel hybrids with pyrazole ring, in this work we synthesized twenty pyrazole-carboxylic acids and twenty pyrazole-carboxamides, using simple synthetic methods, to be used as building blocks in the development of new structures.

Unveiling Potent Photooxidation Behavior of Catalytic Photoreductants

We describe a photocatalytic system that reveals latent photooxidant behavior from one of the most reducing conventional photoredox catalysts, N-phenylphenothiazine (PTH). This aerobic photochemical reaction engages difficult to oxidize feedstocks, such as benzene, in C(sp2)-N coupling reactions through direct oxidation. Mechanistic studies are consistent with activation of PTH via photooxidation and with Lewis acid cocatalysts scavenging inhibitors inextricably formed in this process.

Electrophotocatalysis with a Trisaminocyclopropenium Radical Dication

Visible-light photocatalysis and electrocatalysis are two powerful strategies for the promotion of chemical reactions. Here, these two modalities are combined in an electrophotocatalytic oxidation platform. This chemistry employs a trisaminocyclopropenium (TAC) ion catalyst, which is electrochemically oxidized to form a cyclopropenium radical dication intermediate. The radical dication undergoes photoexcitation with visible light to produce an excited-state species with oxidizing power (3.33 V vs. SCE) sufficient to oxidize benzene and halogenated benzenes via single-electron transfer (SET), resulting in C?H/N?H coupling with azoles. A rationale for the strongly oxidizing behavior of the photoexcited species is provided, while the stability of the catalyst is rationalized by a particular conformation of the cis-2,6-dimethylpiperidine moieties.

L -(-) -Quebrachitol as a Ligand for Selective Copper(0)-Catalyzed N-Arylation of Nitrogen-Containing Heterocycles

l-(-)-Quebrachitol (QCT) has been found as a ligand of copper powder for selective N-arylation of nitrogen-containing heterocycles with aryl halides. Furthermore, another potential catalytic system (copper powder/QCT/t-BuOK) was successfully adapted to unactivated aryl chlorides.

Copper-catalyzed C–N cross-coupling of arylboronic acids with N-acylpyrazoles

A copper-catalyzed C–N bond forming reaction of arylboronic acids and N-acylpyrazoles was developed. This procedure used N-acetyl protected pyrazoles as starting material instead of free pyrazoles (NH). The reaction worked under neutral conditions and did not require any base or ligand. The reaction showed good functional group tolerance.

Phosphinodefluorination of polyfluorobenzenes by silylphosphines Ph(R)PSiMe3 (R = Me, Ph): Further experimental and computational evidences for the concerted ANDN mechanism of aromatic nucleophilic substitution

Trimethylsilylphosphines PhRPSiMe3 (1 R = Me, 2 R = Ph) have been shown to phosphinodefluorinate 1,2,3- (3), 1,3,5- (4) and 1,2,4-trifluorobenzene (5) in benzene solution or without solvent at 150-200 °C to form the respective (difluorophenyl)methylphenyl- and -diphenylphosphines in high NMR yields under harder conditions compared to the previously reported reactions of Me2PSiMe3 with the same substrates. Hexafluorobenzene (6), pentafluorobenzene (7) (at 150 °C), octafluorotoluene (8) and pentafluoropyridine (9) (at 20 °C) react with phosphine 2 without a solvent almost quantitatively under fluorine 1,4-disubstitution (for 6) or monosubstitution (for 7-9) by the Ph2P group to give the corresponding (polyfluoroaryl)diphenylphosphines in 50-60% (for 6-8) and 95% (for 9) isolated yields. The regio and substrate selectivities exhibited by 3-5 in the reactions of the single substrates and in competitive reactions of 3 vs. 4 with 1 or 2 and 4 vs. 5 with 2 indicate relative fluorine substituent rate factors fo-F > fm-F consistent with the concerted ANDN mechanism which is supported by high level quantum chemical DFT-studies for the reactions of the substrates 3 and 4 with 1, 2 and 10 as well as for 6 with 2.
