Abstract

Abstract: Herein, we report the synthesis of N-tert-butoxycarbonyl (BOC) protected [V6 O13 {(OCH2 )3 C–NH2 }2 ] 2− built from the Lindqvist-type hexavanadate. The reaction of di-tert-butyl dicarbonate (BOC2 O) with tris(hydroxymethyl)aminomethane (Tris) led to the organic derivative [(OCH2 )3 C–NH(BOC)] that reacts with the decavanadate in dimethylacetamide (DMA) to form the [V6 O13 {(OCH2 )3 C–NH(BOC)}2 ] 2− anion. The tetrabutylammonium (TBA + ) salt of this hybrid polyoxovanadate, TBA2 [V6 O13 {(OCH2 )3 C–NH(BOC)}2 ]· 2DMA, has been characterized in the solid-state by single-crystal X-ray diffraction and infrared spectroscopy, and in solution by multinuclear ( 1 H, 13 C, 15 N and 51 V) and DOSY NMR, and UV–visible spectroscopy.
