Iridium-catalyzed intermolecular amidation of sp3 C-H bonds: Late-stage functionalization of an unactivated methyl group

Reported herein is the iridium-catalyzed direct amidation of unactivated sp3 C-H bonds. With sulfonyl and acyl azides as the amino source, the amidation occurs efficiently under mild conditions over a wide range of unactivated methyl groups with high functional group tolerance. This procedure can be successfully applied for the direct introduction of an amino group into complex compounds and thus can serve as a powerful synthetic tool for late-stage C-H functionalization.

Studies on Transition-metal Oxo and Nitrido Complexes. Part 9. Periodato and Tellurato Oxo-ruthenium Complexes as Organic Oxidants. X-Ray Crystal Structure of trans-NaK5*8H2O

Salts of the anion trans-6-, earlier formulated as 6-, and of 6- have been prepared, and the X-ray crystal structure of the complex trans-NaK5*8H2O determined .Vibrational and electronic spectra for these diamagnetic 'ruthenyl' complexes are also reported.The periodato complexes function as overall six-electron oxidants in aqueous solution, converting primary alcohols to carboxylic acids and secondary alcohols to ketones; such reactions can be rendered catalytic if periodate is used as a co-oxidant.The tellurato complex functions as a two-electron oxidant for alcohols.

Oxo Complexes of Ruthenium(VI) and (VII) as Organic Oxidants

Oxidation of a variety of saturated and unsaturated primary and secondary alcohols by tetraoxoruthenate(VI), 2-, tetraoxoruthenate(VII), -, barium trans-trioxodihydroxoruthenium(VI), trans-Ba, dioxotrichlororuthenate(VI), -, and dioxodichlorobipyridylruthenate(VI),, has been studied; 2- may be used catalytically in conjunction with 2- under basic aqueous conditions.For some of these systems, the oxidation of several aldehydes and amines were also examined.Both 2- and - oxidise primary alcohols to carboxylic acids and secondary alcohols to ketones; the reactivity of these reagents towards unsaturated alcohols was studied in particular.The new species and also cleanly oxidise a wide range of alcohols to aldehydes and ketones without attack of double bonds.Ba functions as a heterogeneous oxidant in dichloromethane, oxidising only the most reactive alcohols to aldehydes.
