Per my reaction system outline above, the Fe ll is converted into red Fe lll in proximity to the anodic aluminum zone in the electrochemical cell. An interesting and important variation from my experimentation here for future work, is that one could substitute for carbonate, say a nitrate especially aqueous NH4NO3, a possible nitration reaction could occur without any mineral acids required!

Caution: many organic nitrates like CH3NO3 are energetic explosive , highly toxic, and possibly present significant long term health risk even from low doses. Even if one is not intending to create such compounds, please be aware of the risks of working with a nitrate in the presence of an organic in following my reaction path. Mezyk, Thomas D.

Cullen, Kimberly A. Rickman and Bruce J. Alkenes react faster than alkanes, and their rate constants are also faster in nonpolar solution. A linear correlation was found between measured rate constants in water and acetonitrile, which can be used to estimate aqueous nitrate radical rate constants for compounds having low water solubility. And, if sourced from KNO3, it is also safe and seemingly innocuous.

But all this, of course, rests on my proposed path actually working. Here is a side by side reaction results: The carbonate radical treated solution on the right may have indeed created a carbonate salt, looks like FeCO3, but I will test.

It is fluffy and a bit off-white, not resembling Al OH 3, in my opinion, which is in accord with the largely untarnished appearance of the Al foil. The carbonate-free run on the left appears to have created a reddish fluffy precipitate suggesting a ferric ion.

The Al foil has lost most of its luster. To quote parts: First, as to my choice of employing an electrochemical cell for synthesis: "The method is preferably used in synthesis, but can also be useful in the destruction of pollutants etc. In certain embodiments of this nature, the use of external current applied to the system is not necessary, and a simple galvanic cell can be set up. I would also note that the underlying presence of an encompassing commercial patent apparently supporting my suggested path, or at least a variation thereof, may indicate more than just theoretical interest.

My assessment is that the products are likely consistent with the reference I cited. Member Is Offline Mood: Semi-victorious.

NOTE: Important charges and non-bonding electrons are shown throughout the animation except during the transition phase. This example of a pinacol coupling shows the dimerisation of acetone to give a diol 2,3-dimethylbutane-2,3-diol. In aprotic solvents such as benzene the concentration of the ketyl radical builds up leading to dimerisation.

The use of a metal such as magnesium or aluminium allows the reaction to occur more easily by forming covalent metal-oxygen bonds which reduces repulsion between anions. Observe the difference in charge upon the oxygen in the ketyl radical compared to the acetone oxygen.
