Gelation-free synthesis of high-molecular-weight hyperbranched aromatic polymers containing silicon by Suzuki-Miyaura polycondensation of tri- or tetra(bromoaryl)silane with arylenediboronate

Suzuki-Miyaura polycondensation of tri- or tetra(bromoarylsilane) 1 with arylenediboronic acid (ester) 4 in the presence of tBu3PPd precatalyst 3 was investigated for the synthesis of silicon-containing hyperbranched aromatic polymers by...
