Metathesis Polymerisation of Alkynes

Ring Opening Metathesis Polymerisation and Related Chemistry

Part of the book series: NATO Science Series ((NAII,volume 56))

Abstract

The Schrock type tungsten carbyne complexes Np3W=CtBu, (tBuO)3W=CtBu and Cl3(dme)W=CtBu catalyze the polymerization of 1-alkynes. The polymerization of disubstituted alkynes was only successful with Cl3(dme)W=CtBu as catalyst. The Acyclic Diyne Metathesis Condensation (ADIMET) of conjugated or non conjugated diynes is catalyzed by the carbyne tungsten(VI) complex (tBuO)3W=CtBu or W2(tBuO)6. Without or with small amounts of solvent high molecular weighted polyalkynameres were formed. Predominantly mixtures of oligomeres or cycloalkynes were produced, by using higher amounts of solvent.
