Conclusions

  1. 1.

    It was proved by x-ray diffraction analysis that the reaction of 2-isobutenylthiophene with dimethyl diazomalonate leads to the formation of 2-isobutenylthiophenium bis (methoxycarbonyl) methylide.

     
  2. 2.

    The thiophenium ring in this ylide has an envelope conformation, and the planes of the dimethyl malonate and isobutenyl groups form dihedral angles of 92.4 and 19.4°, respectively, with the mean-square plane of the heterocycle.
