STUDIES IN SILICO-ORGANIC COMPOUNDS. III. THE PREPARATIONS AND REACTIONS OF SILICON ANALOGS OF CERTAIN ALIPHATIC ORTHOESTERS¹

Low-Refractive-Index Deep-Ultraviolet Transparent Poly(fluoroalkyl-co-methylsilsesquioxane) Resins Synthesized by Cosolvent-Free Hydrolytic Polycondensation of Organotrimethoxysilanes

“…For each sample, R L–L and R c were consistent with each other, and the data points fell on the line with R L–L = R c . Figure also shows the reference data for silica glass, perfluoroalkanes, − alkylsilanes, ,, poly­(Et-SQ), poly­(dimethylsiloxane), , poly­(tetrafluoroethylene), , and poly­(methyl methacrylate) derived from the literature values of n D , ρ, and R c . These data also lie on the R L–L = R c line.…”

STUDIES IN SILICO-ORGANIC COMPOUNDS. IV. THE ACTION OF ORGANIC ACID HALIDES AND OF HYDROHALOGEN ACIDS ON SILICO-ORTHOESTERS1

“…Polyalkoxysilicon acylates have already been prepared (9). It seemed of interest to study the reaction of one or two of these compounds with an acyl halide to determine the course of the reaction.…”

Steric Hindrance in Highly-Substituted Organosilicon Compounds. Ii. Amine, Ester, and Sulfide Derivatives in the Tri-O-Tolylsilyl Series

“…Post and Hofrichter (18) were able to prepare mixed ester-anhydride types by treating ethyl silicate and related compounds with acetic anhydride. However, we found that tri-otolylethoxysilane does not react with boiling acetic anhydride, with boiling acetic anhydride in the presence of hydrogen chloride, nor with benzoyl or 3,5-dinitrobenzoyl chlorides at 200°.…”
