A new bistriflate monomer was prepared. The bistriflate was copolymerized with new organostannane comonomers under palladium 0 catalysis. The triflate monomer was also reacted with bisphenol compounds under basic conditions to afford polyaryl ethers. The synthesis of polymers using a transition metal catalyzed cross-coupling reaction has become a growing and very productive area of polymer chemistry. Polycondensations using a transition metal catalyzed cross-coupling reaction follow polymerization rules governing stepgrowth processes, and thus, reaction efficiency and monomer purity are critical issues. As part of our polymer synthesis program we have been exploring the use of palladium 0 catalyzed polycondensation of organostannane and aryl halide partners.
