Polyorganosiloxanes are characterized by high flexibility of macromolecules and weak intermolecular interaction. The introduction of various boronic acids into siloxane matrices can lead to an increase in the strength properties of materials based on them due to the formation of both hydrogen and donor-acceptor bonds between boron centers and oxygen atoms. We obtained compound 1, on the basis of which we carried out hydrothiolation and hydrosilylation reactions. The protective group can be easily removed with water to form phenylboronic acid derivatives. The resulting substances were characterized by NMR spectroscopy and IR spectroscopy, mass spectrometry or GPC, TGA and DSC.
