Abstract: We investigated the oscillating chemical reaction of NaBrO3-CH2 (COOH)2-CuL2+-H3PO4 system, where [CuL2+] is [Cu(Me6[l4]-4,11-dieneN4](ClO4)2 · 3H2O.The domain of the existance of the oscillation was obtained in the coordinates of NaBrO3 and CH2(COOH)2. The effects of initial concentration of the components on the oscillation were studied.Various re-ductants (HOOCCOOH, Vcetc) can influence the oscillations.So HBrO2 is an important intermediate.When Ag+, Hg2+(4× 10-5 mol/L) were added to the oscillating system, the oscillations were quenched immediately.It seems that Br- plays the role of a control intermediate as in B-Zsystem catalyzed by Ce4+ or Mn2+, In this system, the oscillations were also inhibited by acrylamide, H2O2 etc.This shows that the free radical may be involved in the reaction process.
