Park, Myung Jun published the artcileDirect preparation of hexaalkyldisiloxanes from trialkylsilanes and cyclosiloxanes from dialkylsilanes using potassium superoxide-crown ether, Application of Triisopropylsilanol, the publication is Main Group Metal Chemistry (1999), 22(12), 713-714, database is CAplus.
Trialkysilanes, R1R2R3SiH (R1/R2/R3 = iPr/iPr/iPr, Et/Et/Et, Ph/Me/Me), were readily transformed to the corresponding hexaalkyldisiloxane in high yields with KO2-18-crown-6. Dialkylsilanes, R1R2SiH2 (R1/R2 = Ph/Ph, Ph/Me, n-Oct/Me, c-hex/Me, Et/Et) gave mainly octaalkylcyclotetrasiloxanes under the same reaction conditions.
Main Group Metal Chemistry published new progress about 17877-23-5. 17877-23-5 belongs to alcohols-buliding-blocks, auxiliary class Protection and Derivatization Reagent, name is Triisopropylsilanol, and the molecular formula is C9H22OSi, Application of Triisopropylsilanol.
