Attempt to synthesize a bis-thiolate tungsten alkylidene catalysts with bulky arenethiolates unexpectedly yielded upon activation of DME a pentacoordinated complex of general formula [W(NAr)(CHCMe3)(SAr’)(κ2-O-CH2-CH2-OMe)], which is active towards self-metathesis of cis-4-nonene compared to the parent bis-benzenethiolate.
Résumé
Des essais dans le but de synthétiser un catalyseur bis-thiolate tungsten alkylidène comprenant des arènethiolates encombrés ont permis, via l’activation du DME, la synthèse inattendue d’un complexe de formule générale [W(NAr)(CHCMe3)(SAr’)(κ2-O-CH2-CH2-OMe)], qui s’avère être active vis-à-vis de l’autométhatèse du cis-4-nonène en comparaison avec l’homologue bis-benzènethiolate.
