TL;DR: The mechanism of the reaction, consisting of homolytic decomposition of two molecules of peroxide in the coordination sphere of Co(III), was proposed based on the study of the kinetics of decomposition in α-hydroxethyl peracetate catalyzed by cobalt acetate in a solution of acetaldehyde as discussed by the authors.
Abstract: 1. The mechanism of the reaction, consisting of homolytic decomposition of two molecules of peroxide in the coordination sphere of Co(III), was proposed based on the study of the kinetics of decomposition of α-hydroxethylperacetate catalyzed by cobalt acetate in a solution of acetaldehyde. 2. In the thermal decomposition of α-hydroxyethylperacetate, a homolytic reaction of decomposition of the peroxide with liberation of CH4, and CO2 takes place in addition to the monomolecular heterolytic reaction of formation of acetic acid.

TL;DR: Reaction, initiated by t-butyl peroxide, between normal primary alcohols and unsaturated alcohols with the double bond in the allyl position leads to 1,4-alkanediols, which forms 1∶1 adducts.
Abstract: 1. Reaction, initiated by t-butyl peroxide, between normal primary alcohols and unsaturated alcohols with the double bond in the allyl position leads to 1,4-alkanediols. 2. At molar proportions of saturated alcohol: allyl alcohol: peroxide of 20:1: 0.2–0.3, a reaction time of six hours, and a temperature of 160–170° the yields of 1∶1 adducts range from 50 to 60%.

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.
