Mec hanism of Stable Phosphonate Ester Derived from ۲-fluro Anilin: a Kinetic Study

These reactions hav e not been investigated yet. Herein, we describe a kinetic investigation of a facile synthesis of the reactions between ۱, ۲ and ۳ (as NH-acid) (Figure ۱) [۱,۲]. Numerous kinetic in vestigations over a large area of different reactions have been reported previously using UV analysis [۱,۵]. To gain further insight into the reaction mechanism, a kinetic study of the reactions was undertaken by UV spectrophotometeric technique.Material and Methods Dialkylacetylenedicarboxilates, triphenylphosphite and ۲-floro Anilin were purchased from Fluka (Buchs, Switzerland) and used without further purification. All extra pure solvents including dichloromethane, ethylacetate and ۱,۲-dichloroethane also were obtained from Merk (Darmstadt, Germany). A Cary UV-Vis spectrophotometer model Bio-۳۰۰ with a ۱۰ mm light-path black quartz spectrophotometer cell was employed throughout the current work.
