Thermal Transformations in Copper/Sodium-Organosiloxanes of a Globular Structure

The thermal and thermo-oxidative transformations in cage-like metal-organosiloxanes of the general formula [RSiO1.5]12[CuO]4[NaO0.5]4 (R= Ph, Me) were studied. It was established that their decomposition occurs in two stages and includes a number of solid-state reactions, leading to the abstraction of organic groups from the silicon atom, the partial or complete reduction of copper atoms, and the release of metallic and oxide phases.
