Usage

Description

2-(4-CHLOROPHENYL)-2-PHENYLACETIC ACID, also known as fenoprofen, is a nonsteroidal anti-inflammatory drug (NSAID) characterized by its ability to relieve pain and reduce inflammation. It functions by inhibiting the production of prostaglandins, which are chemicals responsible for causing pain and inflammation in the body.
Used in Pharmaceutical Industry:
2-(4-CHLOROPHENYL)-2-PHENYLACETIC ACID is used as an analgesic and anti-inflammatory agent for the treatment of conditions such as arthritis. It is effective in managing mild to moderate pain and is available both as a prescription and over-the-counter medication.
However, it is not recommended for long-term use due to the potential for serious side effects, including gastrointestinal bleeding and kidney damage. Therefore, it is crucial to use 2-(4-CHLOROPHENYL)-2-PHENYLACETIC ACID under the guidance of a healthcare professional and to adhere to the prescribed dosage and duration of treatment to minimize the risk of adverse effects.

An Alternative and efficient route to chlorophacinone

A straightforward synthesis for the anticoagulant rodenticide chlorophacinone is described. The short synthesis uses commercially available mandelic acid and 1,3-indanedione as staring materials.

Visible-Light-Driven External-Reductant-Free Cross-Electrophile Couplings of Tetraalkyl Ammonium Salts

Cross-electrophile couplings between two electrophiles are powerful and economic methods to generate C-C bonds in the presence of stoichiometric external reductants. Herein, we report a novel strategy to realize the first external-reductant-free cross-electrophile coupling via visible-light photoredox catalysis. A variety of tetraalkyl ammonium salts, bearing primary, secondary, and tertiary C-N bonds, undergo selective couplings with aldehydes/ketone and CO2. Notably, the in situ generated byproduct, trimethylamine, is efficiently utilized as the electron donor. Moreover, this protocol exhibits mild reaction conditions, low catalyst loading, broad substrate scope, good functional group tolerance, and facile scalability. Mechanistic studies indicate that benzyl radicals and anions might be generated as the key intermediates via photocatalysis, providing a new direction for cross-electrophile couplings.
