Catalysts for silylations with 1,1,1,3,3,3-hexamethyldisilazane was written by Bruynes, Cornelis A.;Jurriens, Theodorus K.. And the article was included in Journal of Organic Chemistry in 1982.Synthetic Route of C8HBr4NO2 This article mentions the following:
Saccharin, Na saccharin, 4-MeC6H4SO2NHP(O)(OC6H4NO2-4)2, [PhOP(O)]2NH, Cl3CCONHP(O)(OC6H4NO2-4)2, etc. are effective catalysts for silylation with Me3SiNHSiMe3. Thus, treating BzOH with Me3SiNHSiMe3 in the presence of saccharin gave 92% BzOSiMe3. In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7Synthetic Route of C8HBr4NO2).
4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. Indole exists overwhelmingly in the 1H-indole form as do other simple indoles. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Synthetic Route of C8HBr4NO2
