Spectroscopically tracing the reactions of octahydridosilsesquioxane (H8Si8O12) with organic molecules

Abstract

AbstractThis article studies the reactions and mechanisms of H8Si8O12 (T8H8) molecules with n‐propanol, acetone, allyl alcohol, n‐butylamine, allylamine, acetic acid, and 1‐octene in air, at room temperature, and without catalysts. The reaction between T8H8 and n‐propanol involves both the highly polarized SiO and SiH bonds and results in cage breakage and forming Q4 and Q3 structures with OC3H7 in the reaction product. T8H8 also reacts with acetone, and the resultant product possesses SiOCH(CH3)2. Allyl alcohol is less reactive to cause T8H8 decomposition, and the resultant product contains SiOCH2CHCH2 and SiOCH2(CH2)3CHCH2. However, it is found that basically T8H8 does not react with acetic acid and 1‐octene. In the reactions of T8H8 with n‐butylamine and allylamine, the resultant products contain SiNH(CH2)3CH3 and SiNHCH2CHCH2, respectively. For the reaction with T8H8, allylamine is less active than n‐butylamine. Possible mechanisms for the T8H8 reactions are discussed.
