Beschreibung

Anwendung

Phenylglyoxylic acid can be used as a precursor in the synthesis of:

• O-acyl acetanilides by decarboxylative o-acylation of acetanilides using Pd catalyst.
• Phenylhydroxycarbene by high-vacuum flash pyrolysis.
• 2-arylbenzothiazoles by reacting with o-aminothiophenol using ammonium niobium oxalate (ANO) as a catalyst.
• 3-aryl-2H-benzo[b][1,4]benzoxazin-2-ones by treating with o-aminophenol in the presence of ammonium niobium oxalate catalyst.
• 2-aryl benzothiazoles through potassium persulfate (K₂S₂O₈)-mediated oxidative condensation of benzothiazoles.
