摘要

Experimental conditions have been designed which allowed the use of a fluoride ion selective electrode for the monitoring of reactions that proceed with a moderately fast departure of F- ion, i.e., t(1/2) approximate to 30 seconds, in aqueous solution. The procedure applied in particular to the S(N)A(R) substitution of 1-fluoro-2,4-dinitrobenzene with p-chlorophenoxide ion and to the hydrolysis, catalyzed by oximate ions, of three organofluorophosphorus esters, namely sarin, soman and diisopropylphosphorofluoridate (DFP). Depending upon the system at hand, the required buffering of the solutions can be made up from the nucleophile reagent itself or through the use of an external buffer. [References: 33]
