11B NMR shifts to halogen substitution in the ten-vertex nido and arachno series of boron clusters. Linear behavior of NMR effects]]>

摘要

Graphical abstractA new ASC method is applied to all the known monohalogeno derivatives of the 10-vertexnidoandarachnoseries to confirm a linear correlation between the universal αrefshifts and all other Δδ(11B) shifts induced in cluster positions.Display OmittedHighlights?Alpha shift correlation (ASC) method was developed for quantitative assessment of NMR substitution effects.?Linear correlation between the universal αrefshifts and Δδ shifts induced in substituted positions.?Thegfactor reflects the sensitivity of a given cage position to substituent changes at the substituted B-vertex.?Individual boron clusters sharply differ ingvalues for specific cage positions.?
