Possibility of synthesis of stereoregular cis-hexaphenylcyclohexasiloxane in inorganic media is shown. The interaction of framework oligophenylnickelsodiumsiloxane with carbonic acid can be considered as a method for preparation of functional organosiloxane macrocycles using “green” chemistry methods. The process does not use organic solvent in contrast to known methods, and the reaction proceeds just several minutes. The structure of the target product was identified by NMR and IR-spectroscopy, X-ray diffraction analysis, size-exclusion chromatography.
