摘要:
Process for converting a geminally substituted cyclopentadiene containing 2-6 substituents into a non-geminally substituted cyclopentadiene by reacting the geminally substituted cyclopentadiene with a base, sodium or potassium at a temperature of 0-200.degree. C. The invention also relates to mixtures of non-geminally substituted cyclopentadienes obtained by means of this process.
