The (6-7,8-9)-dibenzo-2,3-dimethyl-5-germa [4.4]-spironona-1,3-diene 6, the first representative of a new type of germole, has been synthesized. This spirogermole reacts with maleic anhydride and t-butylphosphaacetylene by [2 + 4] cycloadditions, which involve exclusively the 2,3-dimethylgermole moiety. The adduct 9 obtained with the phosphaalkyne undergoes a thermal decomposition leading to the corresponding phosphabenzene.
