The reaction of RLi ( R=nBu,tBu,PhLi ) with 1,1,3,4-tetramethylsilole or germole in THF gives via a ligand exchange ( SN-Si or Ge ) the 1-R-1,3,4 trimethylmetalloles or the 1,1-di-R-3,4-dimethylmetalloles (A).Metalation of MMe groups is not observed but a partial (nBuLi,PhLi) or important (tBuLi) isomerization of metalloles into the transoid exocyclic dienes (B) occurs.
