Composites and Materials Prepared from Boron Cluster Anions and Carboranes

Abstract

Here, we present composites and materials that can be prepared starting with boron hydride cluster compounds (decaborane, decahydro-closo-decaborate and dodecahydro-closo-dodecaborate anions and carboranes). Recent examples of their utilization as boron protective coatings including using them to synthesize boron carbide, boron nitride, metal borides, metal-containing composites, and neutron shielding materials are discussed. The data are generalized demonstrate the versatile application of materials based on boron cluster anions and carboranes in various fields.

Compactability Regularities Observed during Cold Uniaxial Pressing of Layered Powder Green Samples Based on Ti-Al-Nb-Mo-B and Ti-B

“…To enhance their physical and mechanical properties, these alloys are modified with a small amount of boron [8][9][10], which is a structure-modifying impurity in the intermetallic compound. For example, materials based on Ti-43Al-6Nb-1Mo-1Cr-(0, 0.6)B were manufactured [11], and it was observed that the addition of boron, along with a multi-stage forging process, improves the microstructure and significantly increases the ultimate tensile strength of alloys.…”

Iridium-catalyzed selective arylation of B(6)–H of 3-aryl-o-carboranes with arylboronic acid via direct B–H activation

“…Carboranes are a class of carbon–boron molecular clusters with three-dimensional aromaticity, which have been a kind of important building block in functional materials, 1 key frameworks in boron neutron capture therapy agents, 2 and ligands in organometallic as well as coordination chemistry. 3 Therefore, developing methods for selective functionalization of the B–H bond of o -carboranes has drawn more and more interest from chemists and achieved much advancement in recent years.…”
