DERIVATIVES OF PHOSPHORUS ACIDS CONTAINING A P-F BOND. ALKYLDIFLUOROPHOSPHINES AND THEIR REACTIONS WITH ALCOHOLS,
Abstract
Phosphorus acid derivatives containing a P-F bond and alkyldifluorophosphines reactions with alcohol were studied. While searching for a method of synthesizing gaseous methyl- and ethyldifluorophosphines which would be suitable in laboratory conditions, the authors found that these compounds are formed with a yield of 80-85 percent during the interaction of the corresponding alkyldichlorophosphines with antimony trifluoride in a medium of pyridine, which favors the ion-exchange reaction. In order to study the chemical properties of alkyldifluorophosphines the authors investigated the interaction of one representative of this class of compounds - methyldifluoropnosphine - with alcohol. The experiment showed that in the presence of dialkylaniline the metal difluorophosphine will form adducts 1:1 with alcohols; these adducts are resistant to distillation and under the action of a stronger base - triethylamine - they separate hydrogen fluoride with the formation of tricoordination esterofluoroahydrides of alkylphosphinic acids.
