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.
