that the suggested method is applicable for the oxidation of organic alkylarene derivatives (Ar-CH3, Ar-CH2-R) to the corresponding acids and ketones (Ar-C(O)OH and Ar-C(O)-R), as well as hydride silanes ([Si]-H) to silanols ([Si]-OH). The possibility of synthesizing monomeric (methyl) and polymeric (siloxane-containing PET analogue, Sila-PET) esters based on 1,3-bis( p-carboxyphenyl)disiloxane was

In this work, general approaches for preparing p-tolylsilanes as promising precursors for the synthesis of functionalized organosilicon compounds are discussed. Various synthetic techniques, including new and specially developed ones, were used to obtained p-tolylsiloxanes of different structures. Our findings resulted in advanced methods over the previously reported procedures, since they do not imply

This study reports the development of a selective method for the synthesis of p-tolylsiloxanes, namely, symmetrical disiloxanes and cyclotetrasiloxanes, by hydrolytic condensation of p-tolyl-containing mono(ethoxy)silanes and di(ethoxy)silanes in the presence of [Me4N]+OH–. The reaction occurs under mild and simple reaction conditions: at 30 °C, under atmospheric pressure, in 1–5 h, in acetone and
