Aryl Bis(triflates) in Palladium (0) Cross-Coupling Reactions. Synthesis of Polyphenyl-Alkynyl, Alkenyl, and Aryl Ethers

Abstract

A new bis(triflate) monomer was prepared. The bis(triflate) was copolymerized with new organostannane comonomers under palladium (0) catalysis. The triflate monomer was also reacted with bis(phenol) compounds under basic conditions to afford poly(aryl 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.
