Reactivity of trifluoromethyl carbonyl compounds in a two-step reaction with dialkyl phos-phites (the Abramov reaction and phosphonate—phosphate rearrangement) has been studied and the scope of this reaction for the preparation of O-phosphorylated 1-substituted 2,2,2-trifluoro-ethanols, serine hydrolase inhibitors, has been determined.

with a variety of dialkyl phosphites in the presence (or absence) of a tertiary amine to give the corresponding dialkyl aryl(-alkyl)methyl phosphates in high yields. The reaction of methyl -phenyl ketone with the sodium salt of diethyl phosphite afforded a good yield of diethyl 1-(phenyl)ethyl phosphate. This reaction offers a new supplemental route to various polyfluorinated esters of phosphoric acid

A novel alkoxide-induced nucleophilic trifluoromethylation of carbonyl compounds, disulfides, and diselenides using diethyl trifluoromethylphosphonate is presented. In these reactions diethyl trifluoromethylphosphonate acts as a [CF3-] synthon.

Acetylcholinesterase and butyrylcholinesterase inhibitors are potential cognition enhancers in Alzheimer disease. O,O-Dialkylphosphate inhibitors with 1-substituted 2,2,2-trifluoroethoxy leaving groups were synthesized by phosphonate-phosphate rearrangement. Substituents in the 1-position of the leaving group along with the O-alkyl groups modulated potency and selectivity against acetylcholinesterase, butyrylcholinesterase, and carboxylesterase.
