Abstract

Sila-, germa- and stannacyclopentasilanes could be obtained by reaction of a 1,4-dianionic polysilane with the dimethyl dichlorides of silicon, germanium and tin. With potassium tert-butoxide the cyclopentasilanes could be transformed into dianions, which were converted to bicyclic compounds by reaction with ethylene glycol ditosylate.
