“…Additionally, polymerizations in which the alkyne remains intact have been reported. Yamamoto published the co-polymerization of N -alkynyl pyrroles 304a,b with the di(stanyl)thiophenes 305a,b (Scheme 80, Reaction (3) [128,129,130]). Yamamoto also reported the oxidative polymerization of 307 with TBAPF 6 in 2012 (Scheme 80, Reaction (4) [131]).…”

Heteroatom-substituted alkynes have attracted a significant amount of interest in the synthetic community due to the polarized nature of these alkynes and their utility in a wide range of reactions. One specific class of heteroatom-substituted alkynes combines this utility with the presence of an azole moiety. These N-alkynyl azoles have been known for nearly 50 years, but recently there has been a tremendous increase in the number of reports detailing the synthesis and utility of this class of compound. While much of the chemistry of N-alkynyl azoles mirrors that of the more extensively studied N-alkynyl amides (ynamides), there are notable exceptions. In addition, as azoles are extremely common in natural products and pharmaceuticals, these N-alkynyl azoles have high potential for accessing biologically important compounds. In this review, the literature reports of N-alkynyl azole synthesis, reactions, and uses have been assembled. Collectively, these reports demonstrate the growth in this area and the promise of exploiting N-alkynyl azoles in synthesis.

“…In addition, organometallic polycondensations have recently been employed to obtain copolymers via a bis(trimethylstannyl)thiophene monomer and a dibromo pyrrole monomer. [31][32][33] However, the polymers obtained by the Stille polycondensation had a very low molecular weight. There was no report on preparing poly(thiophene-alt-pyrrole) via a single monomer which contains a metal functional group and a halogen group.…”
