Abstract

The oligomer yield was optimized by such parameters as the physical state of metal compounds (the use of aqueous solutions of metal chlorides and oligophenylene), the concentration of metal salt solutions (27–60 g/l, depending on the nature of the metal), the oligomerization reaction temperature (310–345 K), and optimal concentration of dimethyl sulfoxide additive (2–7 g/l). The possibility of obtaining the inorganic component of hybrid oligomers in structural states that cannot be realized in aqueous solutions has been discovered.
