General description

Benzoyl chloride, an acid chloride, is a commonly used benzoylating agent. The arylation of 1,1- and 1,2-disubstituted activated alkenes using benzoyl chloride in the presence of palladium catalyst has been investigated.

Application

Benzoyl chloride may be used to synthesize:
  • 4-Methoxybenzophenone via acylation of anisole in the presence of cesium-substituted dodecatungstophosphoric acid (Cs2.5H0.5PW12O40) supported on K-10 clay.
  • Benzoylamino acids via acylation of amino acids in the presence of diisopropylethylamine.
  • p-, o-, m-Methylbenzophenones via benzoylation of toluene in the presence of Al-promoted sulfated zirconia catalysts.

Viruses manipulate cellular metabolism and macromolecule recycling processes like autophagy. Dysregulated metabolism might lead to excessive inflammatory and autoimmune responses as observed in severe and long COVID-19 patients. Here we show that SARS-CoV-2 modulates cellular metabolism and reduces autophagy. Accordingly
