Abstract

O- oder N-protoniert? Das Bis(μ-hydroxo)divanadium(IV)-substituierte γ-Keggin-artige Polyoxometallat (TBA)4[γ-SiVIV2W10O36(μ-OH)4] (siehe Bild links, TBA=Tetra(n-butyl)ammonium) wurde synthetisiert und durch Kristallstrukturanalyse charakterisiert. Seine Reaktion mit Phenylisocyanat ergab (TBA)4[γ-SiVIV2W10O38(μ-OH)2(PhNHCO)2], das zwei N-protonierte Phenylisocyanat- Einheiten enthält und die Cyclotrimerisierung von Phenylisocyanat katalysiert.
