And the article contained the following:
Metal-catalyzed C-N bond formation reactions via acylnitrene transfer have recently attracted much attention, but direct detection of the proposed acylnitrenoid/acylimido M(NCOR) (R = aryl or alkyl) species in these reactions poses a formidable challenge. Herein, the authors report on Ru(NCOR) intermediates in C-N bond formation catalyzed by [Ru(IV)(Por)Cl2]/N3COR, a catalytic method applicable to aziridine/oxazoline formation from alkenes, amination of substituted indoles, α-amino ketone formation from silyl enol ethers, amination of C(sp3)-H bonds, and functionalization of natural products and carbohydrate derivatives (up to 99% yield). Exptl. studies, including HR-ESI-MS and EPR measurements, coupled with DFT calculations, lend evidence for the formulation of the Ru(NCOR) acylnitrenoids as a Ru(V)-imido species. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).COA of Formula: C12H16O7
