“…Carbamate esters (Seiber, 1972;Shafik and Mongan, 1972;Khalifa and Mumma, 1972) and ureas (Miller, 1971) react with trifluoroacetic anhydride to form iV-trifluoroacetyl (TFA) derivatives for trace analysis. The derivatives are less polar, have a greater thermal stability, and are more electron capturing than the starting esters or ureas.…”

“…In plants, these derivatives exist as glucosides, while in animals they are present chiefly as glucuronides and sulfates. KHALIFA and MUMMA (1972) identified aglycone metabolites of carbaryl from plant materials. These metabolites exhibit anticholinesterase activity (KURH and CASIDA 1967).…”

“…Perfluoroacylation, which is frequently employed to enhance the thermal stability of carbamate insecticides (Khalifa and Mumma, 1972;Seiber, 1972; Wong and Fisher, 1975), has been used to quantitate Mesurol and its metabolites (Greenhalgh et al, 1976). Reaction with trifluoroacetic anhydride (TFAA) has revealed that the Mesurol sulfoxide forms a di-trifluoroacetyl (TFA) rivative due to reaction with both the carbamate and sulfoxide moieties.…”
