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
