T. Jelinek et al., MACROPOLYHEDRAL BORON-CONTAINING CLUSTER CHEMISTRY - THE 18-VERTEX MONOCARBABORANE [(ME(3)CNH(2))CB17H18(CN)], Journal of the Chemical Society, Chemical Communications, (23), 1995, pp. 2407-2408
The first definitively characterised macropolyhedral carbaborane speci
es, neutral [(Bu(t)NH(2))CB17H18(CN)], is isolated from the products o
f the reaction between [anti-B18H22] and Bu(t)NC in CH2Cl2; the struct
ure is based on the [anti-B18H22] type of macropolyhedral cluster, wit
h an amine-substituted carbon atom occupying the 9-position in one sub
cluster,
