Contribution to the Chemistry of Boron, 136 [1] A Reinvestigation of the Existence of l,3,2-Dioxaborinium(l-|-) Cations

The chemistry of boron cations was a field long neglected [2]. Meanwhile, many cations containing tetracoordinated boron have been reported [3] and their chemistry has been explored. In addition there exists scattered information relating to tri[4-8] and dicoordinated [9, 10] boron cations. Unlike carbenium ion chemistry their role in boron chemistry is not yet well understood. This situation, ...

Boron chemistry in a new light

Photocatalysis has recently opened up new avenues for the generation of radical species under visible light irradiation conditions. A particularly fascinating class of photocatalyzed transformations relies on the activation of stable boron species with visible-light since it allows the creation of boryl and/or carbon radicals through single electron transfer or energy transfer without the need ...

Recent progress in boron nanomaterials

Various types of zero, one, and two-dimensional boron nanomaterials such as nanoclusters, nanowires, nanotubes, nanobelts, nanoribbons, nanosheets, and monolayer crystalline sheets named borophene have been experimentally synthesized and identified in the last 20 years. Owing to their low dimensionality, boron nanomaterials have different bonding configurations from those of three-dimensional b...

Progress in metathesis chemistry

In contrast to the production of simple bulk chemicals and polymers, which started shortly after the discovery of the “olefin scrambling” reaction, it was not until much later that this transformation was “rediscovered” by the academic world. In the last decade of the 20th century, the so-called olefin metathesis reaction gained real significance in advanced organic synthesis [1]. The developme...
