[EN] BIFUNCTIONAL AND POLYFUNCTIONAL COINITIATORS IN DENTAL COMPOSITIONS [FR] CO-INITIATEURS BIFONCTIONNELS ET POLYFONCTIONNELS DANS DES COMPOSITIONS DENTAIRES
A sustainable protocol of olefinmetathesis in non-degassed, undistilled ethyl acetate under air with commercially available self-scavenging ruthenium catalysts is described. Furthermore, a time economical, cost-effective and scalable method of removal of ruthenium residues is presented. Treatment of post-reaction mixtures with an isocyanidescavenger and then with acid followed by a simple filtration
