“…The significant structural variations described in the last paragraph emphasize the need for a robust nomenclature system for such open cages. The 'debor' method [2p,36] -debor, x,y-didebor, or x,y,z,-tridebor (where x, y and z are locants), followed by the name of the closed structure ending with 'ane' (for a neutral borane) and the actual number of hydrogen atoms (in the unsubstituted open-cage parent) in parenthesis. Names of negatively charged species would need to specify hydrido positions, end with 'ate', and have the charge in parentheses.…”

An appraisal of the current IUPAC recommendations for the nomenclature of boranes and related systems has been undertaken. New developments in the field have been investigated and existing nomenclature systems have been adapted to accommodate these new developments. The principal areas considered are stoichiometric and structural nomenclature (including heteroatom and metal-atom subrogation, as well as substitution of hydrogen), conjoined-cage species, supra-icosahedral systems, and sub-icosahedral non-standard structures. Elements of substitutive, additive, and replacement nomenclature systems have been integrated into individual names to address contentious problems in boron nomenclature that have been around for a long time.

“…Inspection of the former equation also indicates that the carbon insertion is accompanied by the a -*• 0 migration of the silyl substituent along the C=C bond of the primary hydroboration intermediate. Ligand exchange between the Me^d erivative and triphenylphosphine yielded the corresponding 9-PPh3-7-(Me3Si)2CH-nido-7-CB10Hu analogue (24) (80% yield),109 the X-ray structure of which is outlined in Figure 3. Bond distances for structurally determined compounds of the |m'do-L-7-CB10H12j type are in Table 3.…”

“…The significant structural variations described in the last paragraph emphasize the need for a robust nomenclature system for such open cages. The 'debor' method [2p,36] for describing open cages is part of IUPAC Recommendations for the naming of open cages. This 'debor' method, combined with Powell descriptors [23] available for the related closo species from which the open structures are derived, is the preferred method of naming such open supra-icosahedral structures (Recommendation 22).…”
