The present invention comprises a general procedure for preparation of polyedric silsesquioxanes. The procedure includes the use of inorganic or organic hydrogen difluorides and polyeters for preparation of polyedric silsesquioxanes at reflux conditions and gives higher yields at a lower concentration of catalysts. The applied catalysts - hydrogen difluorides - are acid catalysts, which is essentially otherwise than in the case of known application of basic catalysts.
