On the Question of Site-Selective Ligand Exchange in Carboxylate-Substituted Metal Oxo Clusters

Reaction of [Ti(4)Zr(4)O(6)(OBu)(4)(OMc)(16)] (OMc = methacrylate) with acetylacetone (acacH) resulted in dissection of the cluster and formation of [Ti(OBu)(2)(acac)(2)] and the smaller cluster [Ti(2)Zr(4)O(4)(OMc)(16)]. In contrast, the same reaction with [Zr(6)O(4)(OH)(4)(OOCR)(12)](2)·6RCOOH (R...

description Reaction of [Ti(4)Zr(4)O(6)(OBu)(4)(OMc)(16)] (OMc = methacrylate) with acetylacetone (acacH) resulted in dissection of the cluster and formation of [Ti(OBu)(2)(acac)(2)] and the smaller cluster [Ti(2)Zr(4)O(4)(OMc)(16)]. In contrast, the same reaction with [Zr(6)O(4)(OH)(4)(OOCR)(12)](2)·6RCOOH (R = Et, CH(2)CH=CH(2)) led to site-selective substitution of two carboxylate ligands and formation of isostructural [Zr(6)O(4)(OH)(4)(OOCR)(12–x)(acac)(x)](2)·6RCOOH (x ≤ 1).
