boranetransfer

Boranetransfer is a term encountered in chemical literature to describe processes that move boron-containing groups or boron atoms between molecules or within a molecular framework. Because there is no universally accepted definition, the precise meaning varies by context. In organoboron chemistry, boranetransfer often refers to transmetalation-like steps in which a boron substituent is redistributed between species, enabling the assembly of organoboron compounds that serve as intermediates in cross-coupling and other transformations.

In materials science, boranetransfer may describe the transfer or migration of boron within a solid or polymer, such as during doping of carbon materials with boron or during rearrangements in boron-rich materials and glasses. Mechanisms are diverse and can include ionic transfers, radical- or electron-assisted exchanges, and coordination-driven rearrangements. Because of this variety, experimental conditions and substrates vary across reports.

Applications of boranetransfer concepts include the synthesis of complex organoboron frameworks, development of reagents for cross-coupling reactions, polymer functionalization, and the design of boron-containing materials for energy storage or catalysis. The term remains informal in many subfields, and some researchers prefer more specific descriptors like transmetalation, boron migration, or boron-atom transfer when describing particular processes.
