Synthesis of Acylarylenes and Hyperbranched Poly(acylarylene)s by Metal-Free Cyclotrimerization of Alkynes
The present invention provides a new metal-free cyclotrimerization reaction of alkynes to produce a 135-triacylarylene or 135-triacylbenzene. This reaction is catalyzed by secondary amines is strictly regioselective highly functionality-tolerant and the resulting product can be obtained in high yields. This reaction can be further applied for the preparation of novel branched (co)polymers bearing the triacylarylenes as structural units. The preparation of the (co)polymers is carried out as a one-pot single-step reaction procedure giving branched oligomers and polymers in high yields up to 90%. The produced (co)polymers are also processible easily film-forming and thermally stable.
