Decarboxylative Hydroxylation of Benzoic Acids [PDF]

open access: yesAngewandte Chemie, 2021
AbstractHerein, we report the first decarboxylative hydroxylation to synthesize phenols from benzoic acids at 35 °C via photoinduced ligand‐to‐metal charge transfer (LMCT)‐enabled radical decarboxylative carbometalation. The aromatic decarboxylative hydroxylation is synthetically promising due to its mild conditions, broad substrate scope, and late ...

Ruthenium‐Catalyzed C−H Arylation of Benzoic Acids and Indole Carboxylic Acids with Aryl Halides

open access: yesChemistry - A European Journal, 2017
Herein we report the first Ru-catalyzed C–H arylation of benzoic acids with readily available aryl (pseudo)halides. The reaction, which does not require the use of silver salt additives, allows the arylation of previously challenging hindered benzoic ...

Base- and Additive-Free Ir-Catalyzed ortho-Iodination of Benzoic Acids: Scope and Mechanistic Investigations

open access: yesACS Catalysis, 2018
A protocol for the C-H activation/iodination of benzoic acids catalyzed by a simple iridium complex has been developed. The method described in this paper allows the ortho-selective iodination of a variety of benzoic acids under extraordinarily mild ...

First mesomorphic and DFT characterizations for 3- (or 4-) n-alkanoyloxy benzoic acids and their optical applications

open access: yesHeliyon, 2023
New liquid crystalline hydrogen bonded 3- (or 4)-n-alkanoyloxy benzoic acids were synthesized and probed theoretically and experimentally. The molecular structures of these compounds were elucidated by proton NMR, carbon-13 NMR and elemental analyses ...

Selective synthesis of meta-phenols from bio-benzoic acids via regulating the adsorption state

open access: yesiScience, 2023
Summary: Phenols are important building blocks widely applied in many fields. The pronounced orientational effect of the phenolic hydroxyl group makes achieving selective synthesis of meta-phenols challenging.

An effect of positional isomerism of benzoic acid derivatives on antibacterial activity against Escherichia coli

open access: yesOpen Life Sciences, 2021
This study demonstrated the effect of positional isomerism of benzoic acid derivatives against E. coli ATCC 700728 with the serotype O157. The addition of hydroxyl and methoxyl substituents weakened the effect of acids against E.

Approaches to synthesis of ([1,2,4]triazolo[1,5-c]quinazolin-2-yl)benzoic acids as potential anti-inflammators

open access: yesФармацевтичний журнал, 2022
Despite their high efficacy NSAIDs have significant side effects due to non-selective inhibition of COX-1 and COX-2. Due to this, medical chemists still pay considerable attention to their design and synthesis, in particular the creation of hybrid ...

Hydrogenation of benzoic acid derivatives over Pt/TiO2 under mild conditions

open access: yesCommunications Chemistry, 2021
Dearomative hydrogenation of benzoic acid and its derivatives is challenging to achieve selectively. Here, a highly active Pt/TiO2 catalyst which works in the presence of common catalyst poisons, including bi- and tri-benzoic acids, is described.
