Abstract: The metallation of CH-groups in carboranyl polyhedra with n-butyllithium followed by end-capping with chloro(di-methyl)vinylsilane was explored using a model B-substituted organosilicon derivative obtained previously, the optimal conditions being Et₂O, –10 →20 °C, total processing time 125 min. This procedure was applied to prepare a zero-generation polyfunctional B-substituted carborane-carbo-silane dendrimer G₀-4 cages.

Keywords: carbosilanes, dendrimers, carboranes, CH-functionalization, metallation, core–shell, organosilicon compounds.
