The 19 F NMR chemical shifts (δF) of the p-ZPhCHFCO2CHL1L2 esters of 2-fluoro-2-substituted aryl acetic acids have been measured.The δF values of the two diastereoisomers of these esters are linearly related to the ?+ Brown-Okamoto substituent parameters for each term of the series studied.The configuration of such esters of arylacetic acid can be deduced from their δF values when compared to those of esters derived from the non-substituted acid of known configuration.
