The invention relates to a process for the preparation of a compound of the formula IV or IVa [ STR 1 ] in which R.sup.1 -R.sup.5 are preferably hydrogen or alkyl, which comprises reacting a compound I [ STR 2 ] with a compound II [ STR 3 ] in which X.sup.1 and X.sup.2 are preferably halogen, to giv
The invention relates to a process for the preparation of a compound of the formula IV or IVa [ STR 1 ] in which R.sup.1 -R.sup.5 are preferably hydrogen or alkyl, which comprises reacting a compound I [ STR 2 ] with a compound II [ STR 3 ] in which X.sup.1 and X.sup.2 are preferably halogen, to give the corresponding indanones, which are converted into the compounds IV and IVa by reduction and dehydration. The compounds IV and IVa are important intermediate products for the preparation of chiral metallocene complexes which are suitable catalyst components for olefin polymerization.
