DOI: 10.1021/acs.inorgchem.2c00428
Abstract: We demonstrate reactivity between a β-diketiminate-supported niobium(III) imido complex and alkyl azides to form niobatetrazene complexes (BDI)Nb(NtBu)(RNNNNR) (BDI = N,N-bis(2,6-diisopropylphenyl)-3,5-dimethyl-β-diketiminate; R = cyclohexyl (1), benzyl (2)). Intriguingly, niobatetrazene complexes 1 and 2 can be interconverted… read more here.

DOI: 10.1021/acscatal.6b02694
Abstract: Metal–imido complexes are critical intermediates in transition metal-catalyzed C–H amination reactions. Discerning the factors that control their reactivity, however, remains largely open for exploration, particularly for the territory of cobalt–imido’s. Herein we describe a systematic… read more here.

DOI: 10.1039/d2sc02706b
Abstract: In this Perspective, we discuss the strategy of π-loading, i.e., coordination of two or more strongly π-donating ligands to a single metal center, as it applies to promoting reactivity at group 5 transition metal-imido groups.… read more here.
