ABSTRACT:
The present invention relates to supported catalysts based on Re2O7/(—Al2O3for use in the preparation of cycloalkadienes in a metathesis reaction, a process for preparing cycloalkadienes in the presence of these supported catalysts and also the use of the resulting cycloalkadienes for preparing fragrances.
