REAGENT FOR DETERMINING FLUORINE ION AND QUANTITATIVE ANALYSIS OF FLUORINE ION

摘要

PROBLEM TO BE SOLVED: To obtain a new reagent for determining fluorine ion, capable of quantitatively providing a fluorescent compound and detecting fluorine ion in high sensitivity by selectively reacting with only fluorine ion in a sample. ;SOLUTION: This compound is represented by formula I [R₁ is H or OCH₃; R₂ and R₃ are each H, or CH₃; R₄ to R₆ are each CH₃ or C(CH₃)₃; S is H, OCH₃ or OC₂H₅], e.g. 3-(2-t-butyldimethylsiloxy-1-naphtyl)-propenoic ester. Furthermore, the compound of formula I is obtained by reacting a compound of formula II with a compound of the formula ClSiR₄R₅R₆ in an inert organic solvent in the presence of a base such as triethylamine.;COPYRIGHT: (C)1998,JPO
