Reactions of [o-(fluorodimethylsilyl)phenyl]lithium (1) with GeCl2 and SnCl2 produce benzosilagermacyclobutene 2 and benzosiladistannacyclopentene 3, respectively, both of which have o-(fluorodimethylsilyl)phenyl groups on the germanium and tin atoms. The molecular structures of 2 and 3 were determined by X-ray crystallographic analysis, which reveals the structural features of the functionalized four-
