The active metabolites (oxons) of phosphorothionate insecticides can be detoxified via Aesterase hydrolysis. Two enzymes with A-esterase activity have been isolated from rat serum. Whole serum was applied to anion exchange gel (DEAE Sepharose Fast Flow) and incubated (1 hr). Tris-HCl buffer (0.05 M; pH 7.7, at 5 °) containing 0.25 M NaCl was added ...

Phenol acylation on Hβ, CeHβ and SO42-/ZrO2 using acetic acid and acetic anhydride as acylating agents is compared in the temperature range 250-400°C. Acetic acid formed phenyl acetate (PA) and o-hydroxy acetophenone (o-HAP) and acetic anhydride formed p-hydroxyacetophenone (p-HAP ) along with PA and o-HAP. The formation of o-HAP and p-HAP, the pro...

Palladium-catalyzed methods for C-H oxygenation with O2 as the stoichiometric oxidant are limited. Here, we describe the use of nitrite and nitrate sources as NOx-based redox mediators in the acetoxylation of benzene. The conditions completely avoid formation of biphenyl as a side product, and strongly favor formation of phenyl acetate over nitrobe...
