Abstract

Acridine-9-hydroxamicacid 5 is suitable for the analytical detection of the model phosphorylfluorides 7 by fluorescence. The model compounds are rearranged according to Lossen and degradated to the fluorescent 9-aminoacridine 6 using defined reaction conditions. Thiophospho-S-esters (with diethyl-thiophosphinicacid-S-butylester 8 as a model compound) are cleaved to the corresponding phosphoryl-fluorides (a) and mercaptanes (b) by fluorolysis. (a) is identified qualitatively with acridine-9-hydroxamicacid 5, (b) by the Ellman-reaction.

Zum Fluoreszenznachweis der Modellphosphorylfluoride 7 ist Acridin-9-hydroxamsäure 5 geeignet. Die Modellverbindungen 7 werden unter Einhaltung definierter Bedingungen nach Lossen umgelagert und zum fluoreszierenden 9-Aminoacridin 6 abgebaut. Thiophospho-S-ester (Modell: Diethylthiophosphinsäure-S-butylester 8) werden durch Fluorolyse in die entsprechenden Phosphorylfluoride (a) und Mercaptane (b) überführt. (a) wird mit Acridin-9-hydroxamsäure 5 und (b) nach Ellman qualitativ nachgewiesen.
