Reaction of p-Nitrophenyl Diphenyl Phosphate in Cetyltrimethylammonium Fluoride. Apparent Failure of the Pseudophase Model for Kinetics

The reaction of F- with p-nitrophenyl diphenyl phosphate (pNPDPP) is very rapid in aqueous solutions of cetyltrimethylammonium fluoride (CTAF).However, the results do not conform to the pseudophase ion-exchange model because the rate constant does not become constant when the substrate is fully micellar bound, but continues to increase with increasing or with addition of NaF.Added Br- as NaBr or CTABr inhibits reaction showing that Br- displaces F- from the micelle.Reasons for the apparent failure of the pseudophase model are considered.

Electrophilic Fluorination of Secondary Phosphine Oxides and Its Application to P-O Bond Construction

A novel and efficient electrophilic fluorination of secondary phosphine oxides with Selectfluor has been achieved. This transformation provides direct access to phosphoric fluorides in up to 92% yield under mild conditions. In addition, P-O bond construction via a one-pot coupling process of secondary phosphine oxides with water or alcohols in the presence of Selectfluor leads to the formation of phosphinic acids or phosphinates in up to 96% yield.

Single step fluorination of dialkylphosphites: trichloroacetonitrile-KF as an efficient reagent for the synthesis of dialkyl fluorophosphates

The use of trichloroacetonitrile and KF mixture is described as an efficient reagent for the direct conversion of dialkylphosphites to their corresponding dialkyl fluorophosphates via in situ formation of dialkyl chlorophosphates in one-pot.
