Modification of yttrium alkoxides: β-Ketoesterate-substituted yttrium alkoxo/hydroxo/oxo clusters

Add time:09/03/2019 Source:sciencedirect.com
Reaction of Y5O(OiPr)13 (“yttrium iso-propoxide”) with one molar equivalent of isopropyl acetoacetate (iprac) per Y resulted in the formation of Y9O(OH)9(OiPr)8(iprac)8, a rare example of an yttrium alkoxo/hydroxo/oxo cluster. Reaction in a 1:3 molar ratio gave Y4(OH)2(iprac)10 and Y6(OH)6(iprac)12 instead. A fourth cluster, Y9O(OH)9(iprac)16, structurally closely related to Y9O(OH)9(OiPr)8(iprac)8, was obtained upon recrystallization of Y4(OH)2(iprac)10 from CDCl3.
