Silsesquioxanes constitute a diverse range of Si-O frameworks with a wide variety of intriguing possibilities as models for catalysis. These topologically interesting molecules are formed by the hydrolytic condensation of trifunctional organosilanes. Heterosilsesquioxanes are formally derived by sub
18-Hydroxy-11-deoxycorticosterone forms a non-polar dimer under acidic conditions. The dimer was purified by high performance liquid chromatography and further analysed by electrospray mass spectrometry. The purified dimer has a molecular weight of 656 Da with two free ketone groups and no free hydr
