A Diazoalkane Derivative of a Polyoxometalate: Preparation and Structure of [Mo6O18(NNC(C6H4OCH3)CH3)]2

Abstract

A new metathetical route to diazoalkane complexes is described which allows the introduction of such ligands into previously inaccessible environments. The method, which involves the exchange of oxo and [N2 CR2 ] ligands, is illustrated by the preparation of the first diazoalkane-polyoxometalate complex 1.

Diazoalkane complexes of ruthenium with tris(pyrazolyl)borate and bis(pyrazolyl)acetate ligands

“…The yellow-green solid which slowly formed was filtered and crystallised from dichloromethane and diethylether; yield ≥80%. IR (KBr, cm Ru (770.16): C,51.46;H,5.10;Cl,4.60;N,7.27;Found: C,51.61;H,5.19;Cl,4.42;N,7.15%.…”

Rational Synthesis of Covalently Bonded Organic–Inorganic Hybrids

“…The hexamolybdate ion has the so‐called Lindquist structure,12 which features six terminal oxygen atoms aligned along the Cartesian axes. These terminal oxygen atoms are reactive enough to be replaced by various organic species, including the nitrosyl,13 diazenido, hydrazido,14 organometallic,15 diazoalkyl,16 and imido ligands 17–25. For imido derivatives of hexmolybdates, so far, three types of reactions have been discovered; namely, reactions with phosphinimines [Eq.…”

Rationale Synthese kovalent gebundener organisch‐anorganischer Hybdridverbindungen

“…Diese terminalen Sauerstoffatome sind reaktiv genug, um von verschiedenen organischen Spezies ersetzt zu werden, z. B. von Nitrosyl‐,13 Diazenido‐, Hydrazido‐,14 Metallorgano‐,15 Diazoalkyl‐16 und Imidoliganden 17–25. Bislang sind drei Synthesen für Hexamolybdat‐Imidoderivate bekannt: die Reaktionen mit Phosphiniminen [Gl.…”
