HYDRAZIDE-CHELATE CATALYSTS OF THE HOVEYDA-GRUBBS TYPE. INVESTIGATION OF THEIR STRUCTURE AND PROPERTIES
New catalysts for olefin metathesis have been investigated, and the effect of chelate ring expansion in Hoveyda-Grubbs-type catalysts has been considered. Methods for the synthesis of new hydrazide-containing ligands and target ruthenium complexes have been developed, and their structures and properties have been studied. The dependence showing the change in the catalytic activity of catalysts with various substituents has been determined.
