Germene 1 reacts with the CO and CS double bonds respectively of phenylisocyanate and methylisothiocyanate by formal [2+2] cycloadditions, leading to four-membered ring derivatives 2 and 3. With CS2, dithiagermolane 11 and dithiadigermetane 12 are obtained; the first step of this reaction is probably a formal [2+2] cycloaddition between the GeC and CS double bonds. With nitromethane, oxazadigermolidine
