Method of forming polymers

摘要

Methods of metal-catalyzed polymerization are described using a metal catalyst of formula (III): wherein R3 in each occurrence is independently selected from C1-10alkyl and aryl that may be unsubstituted or substituted with one or more substituents; y is 0 or 2; and Z− is an anion. Methods described include Buchwald-type and Suzuki-type polymerization.

1. A method of forming a polymer by polymerising a composition comprising at least one monomer of formula (I) and at least one monomer of formula (II): wherein: R1 comprises an aromatic group that may be unsubstituted or substituted with one or more substituents; R2 independently in each occurrence is a substituent; Ar1 independently in each occurrence is an aryl or heteroaryl group that may be unsubstituted or substituted with one or more substituents; X independently in each occurrence is selected from bromine, chlorine, iodine and sulfonic acid esters, and each X is bound to an aromatic carbon atom of R1; n is a positive integer; m is 0 or a positive integer; and the monomers are polymerised in the presence of a preformed palladium catalyst of formula (III):
[R33P—Pdy+—PR33]yZ−  (III) wherein R3 in each occurrence is independently selected from C1-10 alkyl, phenyl, and phenyl substituted with one or more C1-5 alkyl groups, wherein at least one R3 of at least one group PR33 is C1-10 alkyl and at least one R3 of the at least one group PR33 is phenyl that may be unsubstituted or substituted with one or more C1-5 alkyl groups; y is 0 or 2; and Z− is an anion.
