Polyoxometalates have a wide range of proven utilities and multiple potential applications in chemistry, biology, and material science. There are almost no reports of POMs covalently modified with functional and nontrivial organic groups because such species are very challenging to prepare and purify. Thus, effective routes to such compounds should significantly increase diversity in POM science and applications. We report that vanadium-containing POMs react with alcohols to form hydrolytically stable vanadium esters whose ester functions can be subsequently modified with enantiomerically pure organic groups under mild conditions and in good yield. The resulting chiral catalytically active bis(triester)V6 units are targeted for construction of catalytically active metal organic frameworks (MOFs).
