Cis/Cis-2,5-dipropenylthiophene monomers for high-molecular-weight poly(2,5-thienylene vinylene)s through acyclic diene metathesis polymerization

The synthesis of the 2,5-dipropenylthiophene monomer possessing exclusively cis-double bond configurations through the reduction of a dipropynylthiophene precursor is reported. Lindlar's catalyst is found to be completely ineffective, while a dissolving metal method involving activated zinc is successful in alkyne reduction to cis-alkenes with high yields and excellent selectivity. The acyclic diene metathesis polymerization of the monomer affords the poly(2,5-thienylene vinylene) polymer of a high molecular weight. Copyright
