Mechanochemical Rearrangements

The Journal of Organic Chemistry, 2021
Molecular 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 ...

A Forbidden Rearrangement

Organic Letters, 2003
[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.

Rearrangement Inequalities

Canadian Journal of Mathematics, 1972
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 ...

Rearrangements of "Carbanions"

1987
After 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.

Changing/Rearranging

2022
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.

The Amadori Rearrangement

1955
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,
