The selective catalytic oxidation of silanes to silanols with H₂O₂ activated by the Ti-beta zeolite

Abstract

Ti-beta catalyses the oxidation of small- and medium-sized silanes to the corresponding silanols by aqueous (30%) H₂O₂ as oxygen donor with high conversions and excellent selectivity (no disiloxane).
