Sodium cis-tetratolylcyclotetrasiloxanolate and cis-tritolylcyclotrisiloxanolate: Synthesis, structure and their mutual transformations

Crystalline sodium tolylsiloxanolates and their TMS- derivatives were synthesized. Molecular and crystal structures were determined by single-crystal X-ray analysis and X-ray powder diffraction. The mutual transformation of the compounds into each other has been demonstrated.
