Something germane about germanium: facile access to Ge10 adamantane
Abstract
The all-germanium adamantane (Me3SiGe)4(GeMe2)6 (2) was synthesized from its isomer (Me3GeSi)4(GeMe2)6 (1) via sila-Wagner-Meerwein rearrangement (overall four steps starting from commercial Me2GeCl2, Si2Cl6, and [nBu4N]Cl). The molecular structures of 1 and 2 were characterized by single-crystal X-ray diffraction; a plausible mechanistic scenario is postulated based on quantum-chemical calculations.
