Desymmetrization of N-Sulfonated Aziridines by Alkyllithium Reagents in the Presence of Chiral Ligands

The stereochemical course of the rearrangement of the N-sulfonylaziridines 5, 15, and 25 in the presence of s-BuLi/(-)-sparteine to the bicyclic sulfonamides 4, 16, and 17, respectively, has been investigated chemically and by X-ray structure analysis. Th

Is the Electrophilicity of the Metal Nitrene the Sole Predictor of Metal-Mediated Nitrene Transfer to Olefins? Secondary Contributing Factors as Revealed by a Library of High-Spin Co(II) Reagents

Recent research has highlighted the key role played by the electron affinity of the active metal-nitrene/imido oxidant as the driving force in nitrene additions to olefins to afford valuable aziridines. The present work showcases a library of Co(II) reage

A heterogeneous mercury salt catalyst stabilized by m-carbaborane

Development of reusable heterogeneous catalysts has attracted a great deal of attention for both environmental and atom-economic reasons. In particular, a considerable amount of work has focused on reusable heavy- and rare-metal catalysts in order to limit the use and/or minimize the generation of problematic metal waste upon disposal. Herein is reported the development of a new polysiloxane-linked m-carbaboranylmercury (SiCB-Hg) catalyst, which can be used for various mercury salt-induced reactions such as the regioselective cyclization of 1,3-dienes and allyl alcohols, the intermolecular amination of allyl alcohols with sulfamates, and the cycloisomerization of alkynes. The catalyst can be completely recovered by simple filtration, with residual mercury in the filtrate 0.001% (nearly the quantitative limit). Furthermore, the catalyst can be reactivated by treatment with aqueous HCl and then AgOTf for reuse.

DDQ-mediated direct oxidative coupling of amides with benzylic and allylic sp3 C-H bonds under metal-free conditions

A simple and efficient method for the direct oxidative coupling of amides with benzylic and allylic sp3 C-H bonds using DDQ as an oxidant is described. A range of amides including benzamide, benzyl carbamate, and substituted sulfonamides reacted efficiently with various benzylic and allylic substrates under metal free conditions to afford amidation products in good to excellent yields.
