Five- and seven-membered cyclic active complexes in organic chemistry

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    Five-membered cyclic active complexes were proposed for a number of organic reactions. Here one of the centers in the cycle donates two electrons. This can be either a negative ion of the type of OH− and−OC2H5, or an atom with an unshared pair of electrons.

  2. 2.

    Seven-membered cyclic active complexes were proposed. The role played by one center reduces to the fact that it represents a free orbit. This can be a catalyst of the BF3 type.

  3. 3.

    In all of the discussed cases 6 electrons move in the field of the cycle.
