Base-catalyzed dinitrogen cleavage by molybdenum amides

The amides Mo(NRAr)3 (R=CMe3 or C(CD3)2CH3, Ar=3,5-C6H3Me2) and HMo(η2-Me2CNAr)(NRAr)2 (R=CHMe2 or CH(CD3)2, Ar=3,5-C6H3Me2) are known to effect the six-electron reductive cleavage of dinitrogen in the absence of added reagents to provide terminal nitrido molybdenum complexes of formula NMo(NRAr)3. However, this reaction typically has required a lengthy incubation period at -35°C during which N2 uptake takes place. This work reports on the catalytic effect of addition of stoichiometric amounts of N-heterocyclic bases such as 2,6-dimethylpyrazine, 1-methylimidazole, 4-dimethylaminopyridine (DMAP), and pyridine itself. Certain combinations of molybdenum amide and base lead to complete conversion to NMo(NRAr)3 within minutes at 25°C, 1 atm of N2, in ether or n-pentane solution. Monitoring of reaction progress and probing for possible intermediates has been carried out using 2H NMR spectroscopy, while taking advantage of samples labeled with CD3 groups. In some cases the 2H NMR data are in accord with intermediate base adduct formation, while in other cases adducts are not observed. The effect of potassium hydride in THF as the added base similarly has been investigated. 2002 Elsevier Science B.V. All rights reserved.

Terminal phosphide and dinitrogen molybdenum compounds obtained from pnictide-bridged precursors

The syntheses of molybdenum terminal phosphide and dinitrogen complexes supported by N-iso-propylanilide ligands are not as straightforward as those previously reported for the analogous N-tert-butylanilide complexes. To arrive at these synthetic targets, facile, high-yielding syntheses of bridging pnictide precursors have been developed, and their reduction chemistry has been explored. Cleavage of the reduced μ-E1 compounds was undertaken using CO and N2, providing access to the target compounds.
