Synthese und Eigenschaften von 1,1,3,3-Tetrakis(pentafluorphenyl)-cyclo-di(silthian) und verwandten Verbindungen
摘要:
The synthesis of tetrakis(pentafluorophenyl)-cyclo-di(silthiane) and related compounds by reacting organosubstituted silanes with sulfur or hexamethyldisilthiane is reported The compounds are characterized by analysis, by relative molecular mass, by H-1, C-13, F-19, and Si-29 NMR spectroscopy, and by mass and IR spectra, respectively. Two Si-29 NMR signals of different intensity found for compounds with two different organic substituents on silicon are explained by the existence of diastereomers.
