ALKYNES BEARING FURAN RINGS .1. SYNTHESIS AND POLYMERIZATION WITH MO-BASED CATALYSTS

This paper describes the preparation of new alkynes bearing furanic su bstituents and their polymerization by catalytic systems based on tran sition metal halides in order to obtain novel materials with original properties because of the presence of both furan moieties and alternat e single and double bonds. However, difficulties arising from the spec ific reactivity of the heterocycle in our experimental conditions led us to envisage an indirect way to obtain well-defined products, using an aromatic polymer as the precursor.
