Abstract
The interaction of phenylboronic acid with polyphenylsiloxane and a hydroxy(phenyl)siloxane oligomer has been studied. For the first time, phenylboronic acid was used as a starting material for the production of polyboronphenylsiloxanes under conditions of mechanochemical activation. It has been established that the main side processes induced by activation are abstraction of the phenyl substituent from the boron atom, formation of biphenyl, and trimerization of phenylboronic acid. Since boron compounds (including phenylboronic acid) have biological activity, their introduction into the polymer chain will make it possible to obtain materials with useful properties. For example, boron-containing polymers can be used as coatings to protect against insect vectors of various diseases. The work is fundamental in nature and contributes to revealing and understanding the mechanisms of mechanochemical modification of organosilicon polymers.
