✦ Synopsis

The dibromocarbene or bromofluorocarbene addition to substituted allyldisilanes afforded instable gemdibromocyclopropanes or a gem-bromofluorocyclopropane, respectively. These gem-bromohalogenocyclopropanes undergo a spontaneous ring opening at room temperature to give halogenated dienylsilanes or bromo dienes or dibromotetraenes.
