Nomenclature for boranes and related species (IUPAC Recommendations 2019)
04 September 2020

The most recent IUPAC recommendations concerning boron hydrides and related compounds appeared in 2005. These recommendations reinforced earlier IUPAC recommendations in the subject area that had been published in 1990, but was essentially a ‘holding’ chapter, leaving new recommendations for a subsequent edition.

The Introduction to the 1990 recommendations held that the area of boron nomenclature is ‘contentious’ and ‘specialized’ and that the relevant Chapter (I-11) “is presented as a survey of nomenclature of simpler boron systems because boranes are much discussed even at relatively elementary levels of chemistry, and because we wish to codify those basic principles which seem firmly established”. Many of these recommendations were based on a Technical Report prepared in 1972 by R. Adams. This 1972 report expanded on a brief chapter on the nomenclature of boron compounds in the 1970 recommendations.

The purpose of this present document is to examine existing nomenclature recommendations to ensure that they can be clearly interpreted and to introduce new recommendations, incorporating new developments that have occurred in chemistry since these earlier reports. Each section is organized with numbered Recommendations followed by a more detailed commentary with relevant examples. Substituted boron-hydride cages are named here by a nomenclature that encompasses features borrowed from both ‘substitutive’ and ‘additive’ IUPAC nomenclature systems.

  • Cobaltabis(dicarbollide) ([o-COSAN]−) as Multifunctional Chemotherapeutics: A Prospective Application in Boron Neutron Capture Therapy (BNCT) for Glioblastoma

    25 January 2022 287 hit(s) Biomaterials
    Purpose: The aim of our study was to assess if the sodium salt of cobaltabis(dicarbollide) and its di-iodinated derivative (Na[o-COSAN] and Na[8,8′-I2-o-COSAN]) could be promising agents for dual anti-cancer treatment (chemotherapy + BNCT) for GBM. Methods: The biological activities of the small molecules were evaluated in vitro with glioblastoma cells lines U87 and T98G in 2D and 3D cell models and in vivo in the small model animal Caenorhabditis elegans (C. elegans) at the L4-stage and using the eggs. Results: Our studies indicated that only spheroids from the U87 cell line have impaired growth after treatment with both compounds, suggesting an increased resistance from T98G spheroids, contrary to what was observed in the monolayer culture, which highlights the need to employ 3D models for future GBM studies.
  • Ultrafast Interface Charge Separation in Carbon Nanodot–Nanotube Hybrids

    18 January 2022 284 hit(s) Biomaterials
    Carbon dots are an emerging family of zero-dimensional nanocarbons behaving as tunable light harvesters and photoactivated charge donors. Coupling them to carbon nanotubes, which are well-known electron acceptors with excellent charge transport capabilities, is very promising for several applications.
  • Polylactide, Processed by a Foaming Method Using Compressed Freon R134a, for Tissue Engineering

    17 December 2021 284 hit(s) Biomaterials
    Fabricating polymeric scaffolds using cost-effective manufacturing processes is still challenging. Gas foaming techniques using supercritical carbon dioxide (scCO2) have attracted attention for producing synthetic polymer matrices; however, the high-pressure requirements are often a technological barrier for its widespread use. Compressed 1,1,1,2-tetrafluoroethane, known as Freon R134a, offers advantages over CO2 in manufacturing processes in terms of lower pressure and temperature conditions and the use of low-cost equipment.
  • Endovascular administration of magnetized nanocarriers targeting brain delivery after stroke

    07 December 2021 433 hit(s) Biomaterials
    The increasing use of mechanical thrombectomy in stroke management has opened the window to local intraarterial brain delivery of therapeutic agents. In this context, the use of nanomedicine could further improve the delivery of new treatments for specific brain targeting, tracking and guidance. In this study we take advantage of this new endovascular approach to deliver biocompatible poly(D-L-lactic-co-glycolic acid) (PLGA) nanocapsules functionalized with superparamagnetic iron oxide nanoparticles and Cy7.5 for magnetic targeting, magnetic resonance and fluorescent molecular imaging.
  • Synchrotron-Based Fourier-Transform Infrared Micro-Spectroscopy (SR-FTIRM) Fingerprint of the Small Anionic Molecule Cobaltabis (dicarbollide) Uptake in Glioma Stem Cells

    The anionic cobaltabis (dicarbollide) [3,3′-Co(1,2-C2B9H11)2]−, [o-COSAN]−, is the most studied icosahedral metallacarborane. The sodium salts of [o-COSAN]− could be an ideal candidate for the anti-cancer treatment Boron Neutron Capture Therapy (BNCT) as it possesses the ability to readily cross biological membranes thereby producing cell cycle arrest in cancer cells.   BNCT is a cancer therapy based on the potential of 10B atoms to produce α particles that cross tissues in which the 10B is accumulated without damaging the surrounding healthy tissues, after being irradiated with low energy thermal neutrons.
