Synthesis of hexakis(alkylgermasesquioxane)s from alkyl(chloro)ethoxygermanes and their formation mechanism
Alkyl(chloro)ethoxygermanes were hydrolyzed with water to give 1,3,5-trialkyl-1,3,5-trichlorocyclotrigermoxanes. Hydrolysis of 1,3,5-trichlorocyclotrigermoxanes gave 5,7-dichloro-1,3,5,7,9,1 1-hexaalkyltricyclo[7.3.1.1(3,7)]- hexagermoxanes. The tricylic anti-form ladder hexagermoxanes reacted with water to afford hexakis(alkylgermasesquioxane)s. These cage and ladder germoxanes were identified by spectrospcopic and X-ray diffraction methods.
