Description and Uses
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.
