Site-selectivity in the halogenation of titanium-functionalized polyoxovanadate–alkoxide clusters

Abstract

Herein, we report the synthesis and characterization of a dititanium-functionalized polyoxovanadate–alkoxide cluster. The incorporation of a second heterometal within the cluster core results in striking differences in reactivity of the multimetallic complex. Chlorination of the metal oxide cluster is reported, revealing the directing role of titanium in M–O bond cleavage.
