An acylation reaction based on 2,6-difluorobenzamide and bis(trichloro-methyl)carbonate was carried out to produce 2,6-difluorobenzoyl isocyanate, afterwards the addition reaction with 3,5-dichloro-2,4-difluoroaniline was conducted to synthesize insecticide Teflubenzuron. The overall yield was 75.3%.
The kinetic equation of acylation process fitted first order linear relation.
The scheme initially involves acylation of thiophene using a carboxylic acid to afford the acyl thiophene.
The chemical method include treating with sulfuric acid, saponification, acylation, esterification, etc.
The effects of acylation on stability of red cabbage pigment were studied.
Ethopabate is prepared via esterification, acylation and alkylation from p-aminosalicylic acid in 87.
Loteprednol etabonate was synthesized through oxidation, acylation, hydrolysis and chloromethylation from the starting material prednisolone.
The accepted commercial process is based on 2, 4-difuloroaniline, through coupling, acylation, hydrolysis and carboxylation reactions.
