Implementation And Approach On The Oxidation Of Halogenated Fluorenes By Permanganate In Alkaline Medium With Innovative Mechanism

Abstract

The oxidation kinetics of fluorene (Fl) and its halogenated derivatives, specifically, 2,7-
dichlorofluorene (Fl-Cl), 2,7- dibromofluorene (Fl-Br) and 2,7-diiodofluorene (Fl-I), using potassium
permanganate in alkaline medium has been studied spectrophotometrically at a constant ionic energy
of zero.1 mol dm-three and at 25°C. A first order kinetics has been located in these reactions with
respect to [permanganate]. Fractional-first order dependences of the reactions at the [reductants]
and [alkali] were found out. No great effect on the response costs with the aid of increasing ionic
energy changed into recorded. Intervention of loose radicals was discovered in the reactions. The
reactions mechanism describing the kinetic effects has been proposed which entails formation of 1:1
intermediate complexes between fluorene derivatives and the energetic species of permanganate.
