TL;DR: In this article, a method has been developed for generating free radicals by introducing salts containing complex-forming anions into a system consisting of Cu(II) aquo ions and a hydroperoxide.
Abstract: 1.
A method has been developed for generating free radicals by introducing salts containing complex-forming anions into a system consisting of Cu(II) aquo ions and a hydroperoxide. The radical nature of the reaction has been confirmed by the inhibitor method.
2.
Data have been obtained indicating the formation of hydroxyl radicals in the decomposition of hydroperoxides under the influence of Cu(II) complexes.
3.
Mixed complexes of Cu(II) with hydroperoxides in an aqueous medium are ionic in character, as indicated by results obtained in potentiometric measurements.
TL;DR: In this article, the reaction of 1-alkylcycloalkanols with the Pb(OAc)4-KSCN system, which are oxidized by the ligand transfer mechanism to give oxoalkyl thiocyanates, is described.
Abstract: Oxoalkyl radicals are generated by the reaction of 1-alkylcycloalkanols (ring size C5-C7) with the Pb(OAc)4-KSCN system, which are oxidized by the ligand transfer mechanism to give oxoalkyl thiocyanates.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: Recent progress in the field of organometallic cobalt-catalyzed C–H activation is reviewed until November 2015.
Abstract: Catalytic C–H activation has emerged as a powerful tool for sustainable syntheses. In the recent years, notable success was achieved with the development of cobalt-catalyzed C–H functionalizations with either in situ generated or single-component cobalt-complexes under mild reaction conditions. Herein, recent progress in the field of organometallic cobalt-catalyzed C–H activation is reviewed until November 2015.

TL;DR: This analysis comprehensively review all asymmetric transition-metal-catalyzed methodologies that are believed to proceed via an inner-sphere-type mechanism, with an emphasis on the nature of stereochemistry generation.
Abstract: The development of new methods for the direct functionalization of unactivated C–H bonds is ushering in a paradigm shift in the field of retrosynthetic analysis. In particular, the catalytic enantioselective functionalization of C–H bonds represents a highly atom- and step-economic approach toward the generation of structural complexity. However, as a result of their ubiquity and low reactivity, controlling both the chemo- and stereoselectivity of such processes constitutes a significant challenge. Herein we comprehensively review all asymmetric transition-metal-catalyzed methodologies that are believed to proceed via an inner-sphere-type mechanism, with an emphasis on the nature of stereochemistry generation. Our analysis serves to document the considerable and rapid progress within in the field, while also highlighting limitations of current methods.
