Synthesis of Cyclotetragermanes of the Type of 4 and Conversion to 4. The First Functionalized Cyclotetragermanes

Article abstract of DOI:10.1246/cl.1992.1697

Condensations of R(Ph)GeCl2 (R = t-Bu and R = CEt2Me) with Mg/MgBr2 in THF produced cyclotetragermanes 4, which were converted to 4 by treatment with HCl/AlCl3 or with CF3SO3H followed by CH3COCl.The crystal structure of 4 wa
