Abstract
The influence of experimental conditions and the nature of the catalytic system on the yield of products insoluble in methanol from the carbonyl-olefin exchange reaction (COER) was investigated. It was established that the COER of some α, β-unsaturated carbonyl compounds can be catalyzed by transition metal halides (WCl6, MoCl5), by oxo compounds (WOCl4), and by binary systems (WCl6 + AlCl3, MoCl5 + AlCl3). Under the influence of these catalysts, some α,β-unsaturated ketones can be transformed into conjugated polymers via different pathways. That is why the yield of the polymer product can be higher than calculated on the basis of the simple COER.
