Mechanochemical Rearrangements
The Journal of Organic Chemistry, 2021Molecular rearrangements are a powerful tool for constructing complex structures in an atom- and step-economic manner, translating multistep transformations into an intrinsically more sustainable process. Mechanochemical molecular rearrangements become an even more appealing eco-friendly synthetic approach, especially for preparing active ...

[reaction: see text] A barrelene derivative fragments to afford benzene and trappable 1,2,3-tricyanocyclopropene. The barrelene anion fragments more easily to liberate benzene and the 1,2,3-tricyanocyclopropenyl anion, which is not trappable or stable in solution.

Rearrangements of "Carbanions"
1987After a brief introduction “carbanion” and “carbanion” radical rearrangements are reviewed with special concern to the literature of the last ten years. Radical “anion” systems are included because of the increasing importance of electron transfer reactions.

The final centuries of the Early Formative period (the “Early Horizon,” from ca. 1400–1000 calibrated BCE), represent a time of fundamental transformations on many levels: individual identity, gender, suprahousehold and corporate groups, emerging inequality, and ontologies of human relations with the natural and supernatural worlds.

In recent years a number of inequalities have appeared which involve rearrangements of vectors in Rn and of measurable functions on a finite measure space. These inequalities are not only interesting in themselves, but also are important in investigations involving rearrangement ...

Publisher Summary This chapter discusses the reaction that is the isomerization of an aldosylamine to a 1-amino-1-deoxy-2-ketose. This rearrangement was named after Amadori by Kuhn and Weygand, for Amadori was the first to demonstrate that condensation of D-glucose with an aromatic amine ( p -phenetidine, p -anisidine, or p -toluidine) would yield,

The author presents an algorithm which transforms a function u: [0,\(\ell]\to {\mathbb{R}}\) into its monotone decreasing rearrangement \(u^*\). His construction is motivated by a nice heuristical argument from the buoyant convection of a liquid with variable density.

The paper under review is, in fact, a small, nice and self-contained monograph of 112 pages about the modern state of the art in the theory of rearrangements of series, including series in Banach spaces, topological vector spaces, a.e. convergence of functional series and Fourier series. The origin of the subject is the Riemann theorem that says that a
