Site-selective functionalization of Si₆R₆ siliconoids.

ABSTRACT: The recent progress in the synthesis of partially substituted neutral silicon clusters (siliconoids) revealed unique structures and electronic anisotropies that are reminiscent of bulk and nano surfaces of silicon. Here, we report the selective 2-lithiation of the global minimum Si₆R₆ siliconoid at a different vertex than in the previously reported isomeric 4-lithiated derivative (R = 2,4,6- ⁱ Pr₃C₆H₂). In order to enable an intuitive distinction of the vertices of the global minimum Si₆R₆ scaffold (which can be considered the silicon analogue of benzene in terms of thermodynamic stability), we introduce a novel nomenclature in analogy to the ortho-meta-para nomenclature of d
