Abstract

Abstract Ruthenium based catalysts are versatile promoters of a large variety of reactions. A catalytic system active in metathesis has been generated in situ from [RuCl 2 (p-cymene)] 2, 1, 3-bismesitylimidazolinium chloride, as precursor of a bulky carbene ligand, and cesium carbonate. We report that this three component catalytic system exhibits dichotomous reactivity for the transformation of dienes, providing an active catalytic system for the ...
