Carboranederived

Carboranederived compounds are chemical species that originate from carborane clusters, particularly closo-carboranes such as o-carborane (C2B10H12). The carborane core is a delocalized, three-dimensional boron–carbon framework that acts as a robust, bulky scaffold for attaching functional groups. Carboranederived denotes derivatives in which substituents are installed at boron or carbon vertices while preserving the cage structure. This class spans a wide range of organoboron compounds used to tune properties like stability, lipophilicity, and steric demand.

Functionalization methods include B–H activation and substitution at boron vertices with organic groups, silicon or halogen reagents, and selective reactions at carbon vertices after deprotonation. These strategies enable preparation of carborane-based ligands, reagents, dendritic builders, and multifunctional building blocks.

Applications of carboranederived compounds are diverse. In catalysis, carborane-derived ligands and boron-containing catalysts exploit the hydrophobic, electronically tunable cage to influence reactivity and selectivity. In materials science, they are used in polymers, dendrimers, and dielectric materials due to high thermal stability and low moisture uptake. In medicine, carborane derivatives have been studied for boron neutron capture therapy (BNCT), radiopharmaceuticals, and drug delivery, leveraging high boron content per molecule and the ability to modify biodistribution.

Challenges and outlook include synthesis complexity and cost, as well as purification difficulties. Ongoing research seeks generalized functionalization methods and scalable routes to expand carboranederived libraries, deepen understanding of structure–property relationships, and broaden applications in catalysis, materials, and biomedicine.
