24 Oct 1984TL;DR: In this article, a two-step method for chemically synthesizing substituted butadiene polymers from 1,4-disubstituted butynes is described, where the first step is the polymerization of the butyne monomers and the second is the isomerization to a weak organic base such as triethylamine.
Abstract: A two-step method is disclosed for chemically synthesizing substituted butadiene polymers from 1,4-disubstituted butynes. The first step in the synthesis of the butadiene polymer is the polymerization of 1,4-disubstituted butyne monomers. The substituted butyne polymer which results is then isomerized to the corresponding substituted butadiene polymer by subjecting the butyne to a weak organic base such as triethylamine. The isomerization reaction can be performed under very mild conditions and proceeds at ambient temperature.

TL;DR: In this article, it was shown that 2,3-diarylbuta-1,3dienes were readily obtained in good yields through the S N -2′ type substitution of 1,4-dimethoxybutyne-2 with aryl Grignard reagents in the presence of a copper(I) salt.
