New method for obtaining derivatives of silsesquioxanes (germasilsesquioxanes) with the structure of completely condensed cage with atoms of germanium built in the cage edges

摘要

the object of the application is the way for silseskwioksanu00f3w derivatives (germasilseskwioksanu00f3w) of general formula 2, having a structure completely condensed cage with built-in atoms in germanium edges cage: where r are equal and means alkilowu0105 group from 2 to 4 atom s cof reaction silseskwioksanu (ddsq) with bis (2-methylallyl) in the presence of a lewis acid germananami group triflatu00f3w as catalyst, the reaction is in a mixture of acetonitrile, thf, volume 1: 0.8 to relations from 1: 1.5, preferably 1: 1, using si the way of preparing the reaction mixture.
