No single-phase system has been previously reported to give significant pH oscillations in a closed (batch) reactor. We report here sustained pH oscillations in batch for the Belousov-Zhabotinsky reaction using much lower [H+]0 and much higher [BrO3-

Organozinc compounds prepared from bromomalonic acid esters and zinc react with 3-aryl-2-cyanopropenoic acid primary amides giving a single diastereomer of the corresponding 1-R′-4-aryl-2,6-dioxo-5-cyanopiperidine-3-carboxylic acid esters, or 3-R

We investigated the oscillatory behavior of a BZ system with bromomalonic acid and bromate as substrates and with [Ru(phen)3] SO4 as a catalyst. The observed oscillations can be well modeled with a theory based on two different feedback loops origina

A modified Oregonator model exhibiting photoinduced behavior in the Ru(bpy)32+-catalyzed Belousov−Zhabotinsky (BZ) reaction is presented. We incorporate the concentration of bromomalonic acid as a new variable into the Oregonator model and also tak

Using HPLC technique, two different pathways were found for the oxidation of bromomalonic acid by Ce4+. One route is dominant when the Ce4+ concentration is low compared to that of bromomalonic acid (BrMA). The end products of this reaction route are

Experimental observation shows that bromomalonic acid (BrMA) is one of the sources of photo-induced Br− ion in the photosensitive Belousov-Zhabotinsky reaction. The rate of Br− production by visible light was measured using a Br−-ion-selective

We investigated the number of Ce 4+ ions required to produce one Br ion in the oxidation of bromomalonic acid by Ce 4+ under conditions appropriate to the oscillating Belousov-Zhabotinskii (BZ) reaction. We found a ratio of 1:1, in agreement with ear

In the present mechanistic schemes of the ferroin-catalyzed oscillatory Belousov-Zhabotinsky (BZ) reaction the oxidation of the organic substrates (bromomalonic or malonic acid) by ferriin (the oxidized form of the catalyst) plays an important role.

The relaxation tail of wave profiles in the ferroin-catalysed Belousov–Zhabotinsky reaction was analysed combined with calculations on the basis of a slightly modified Oregonator model. The frequently used rate constant for the reaction between fer
