Protonolysis and Condensation Reactions of Alkoxido-Substituted Lindqvist {MW₅} and Keggin {MPW₁₁} Polyoxometalates: Comparative Experimental and Modeling Studies.

ABSTRACT: An understanding of proton transfer and migration at the surfaces of solid metal oxides and related molecular polyoxometalates (POMs) and metal alkoxides is crucial for the development of reactivity involving protonation or the absorption/binding of water. In this work, the hydrolysis of alkoxido Ti- and Sn-substituted Lindqvist [(MeO)MW₅O₁₈]^3- (M = Ti, 1; M = Sn, 2) and Keggin [(MeO)MPW₁₁O₃₉]^4- (M = Ti, 3; M = Sn, 4) type polyoxometalates (POMs) to hydroxido derivatives and subsequent condensation to μ-oxido species has been investigated in detail to provide insight into proton transfer reactions in these molecular metal oxide systems. Solution NMR studies revealed the dependence of reactions not
