Bismole is a theoreticalheterocyclicorganic compound, a five-membered ring with theformulaC4H4BiH. It is classified as ametallole. It can be viewed as astructural analog ofpyrrole, with bismuth replacing thenitrogen atom of pyrrole. The unsubstituted compound has not been isolated due to the high energy of the Bi-H bond. Substituted derivatives, which have been synthesized, are called bismoles.[1]
2,5-Bis(trimethylsilyl)-3,4-dimethyl-1-phenyl-1H-bismole, for example, can be formed by the reaction of (1Z,3Z)-1,4-bis(trimethylsilyl)-1,4-diiodobuta-2,3-dimethyl-1,3-diene and diiodophenylbismuthine. Bismoles can be used to formferrocene-likesandwich compounds.[2]
