A first compound having an atom in an oxidized state is reacted with a bis(trimethylsilyl) six-membered ring system or related compound to form a second compound having the atom in a reduced state relative to the first compound. The atom in an oxidized state is selected from the group consisting of Groups 2-12 of the Periodic Table, the lanthanides, As, Sb, Bi, Te, Si, Ge, Sn, and Al.

In the thermochemical water splitting process by the CuCl cycle, oxygen gas is produced by a thermolysis process in a three-phase reactor. A precise knowledge of the hydrodynamic and heat transfer analyses is required for the scale-up of the thermolysis reactor. However, in the experimental studies of the scale up analysis, there are some challenges in using the actual materials of the thermolysis reactor products (i.e. molten salt CuCl and oxygen gas). In accordance with the teachings herein, alternative materials are defined, by using dimensional analyses, to simulate the hydrodynamic and heat transfer behaviors of the actual materials. It has been found that these alternative materials are liquid water at 222 C. and helium gas at 902 C. The alternative materials provide safe environment for the experimental runs as well as lower operating temperature. Furthermore, these alternative materials are more readily available and are low cost.

In the thermochemical water splitting process by CuCl cycle, oxygen gas is produced by a thermolysis process in a three-phase reactor. IN accordance with the teachings herein, a technique is provided to achieve the high challenging thermal requirements of the thermolysis reactor, whereby an optimized heat transfer configuration is used. The technique involves using some of the pre-heated stoichiometric oxygen gas produced from the thermolysis reaction, to transfer heat directly to the slurry of molten CuCl and solid Cu.sub.2OCl.sub.2 inside the thermolysis reactor. Experiments were performed to examine the volumetric heat transfer coefficient for the direct contact heat transfer between the gas and the slurry. It was found that the thermal scale up analysis of the thermolysis reactor with direct contact heat transfer, is based on the amount of heat carried by the oxygen gas rather than the amount of heat transferred by direct contact heat transfer.
