Methods to produce B–C, B–P, B–N and B–S bonds in boron clusters
TL;DR: In this review the current methods of producing boron clusters with carbon, B-C, nitrogen,B-N, phosphorus, B -P and sulphur bonds are indicated and there are many existing borane clusters of different sizes, heteroboranes and metallacarboranes.
Journal ArticleDOI
π Aromaticity and Three-Dimensional Aromaticity: Two sides of the Same Coin?
TL;DR: Application of the proposed electronic confined space analogy (ECSA) method to archetypal PAHs leads to the conclusion that the 4n+2 Wade-Mingos rule for three-dimensional closo boranes is equivalent to the (4n-2)π Hückel rule for two-dimensional PAH's.
Journal ArticleDOI
Icosahedral boron clusters: A perfect tool for the enhancement of polymer features
TL;DR: This review focuses on the development of hybrid organic-inorganic π conjugated, silane, siloxane and coordination polymers containing icosahedral boron clusters in the last few decades, which have received considerable academic and technological interest.
Journal ArticleDOI
Are methyl groups electron-donating or electron-withdrawing in boron clusters? Permethylation of o-carborane.
Francesc Teixidor,Gemma Barberà,Albert Vaca,Raikko Kivekäs,Reijo Sillanpää,Josep M. Oliva,Clara Viñas +6 more
TL;DR: At the B3LYP/6-31G* level of theory, it has been proven that the Mulliken charge on each boron after substitution of -H by -Me increases by +0.18 unit, which leads to a high build-up of positive charge upon permethylation, then hampering it.
Journal ArticleDOI
Strikingly long C...C distances in 1,2-disubstituted ortho-carboranes and their dianions.
TL;DR: Cluster carboranes, and possibly other heteroboranes, thus appear to offer unique opportunities for modulating Cc...Cc distances.
