  • Patent number: 6271411
    Abstract: A process is disclosed for preparing 2-aryl-substituted indenes by reacting an indene with an arene compound substituted with an halogen atom, preferably a iodine atom, or with an organosulphonate group, said reaction being carried out in a basic medium in the presence of a palladium catalyst. The compounds obtainable by this process can be used to prepare metallocene compounds with transition metals such as titanium, zirconium or hafnium, which are useful as catalyst components in the polymerization of olefins.

  • Patent number: 6268535
    Abstract: The present invention is a method of preparing a 3-aryl-1-indanamine represented by structural formula I: and physiologically acceptable salts thereof. In structure I, phenyl ring A can be unsubstituted or substituted with 1-4 substitutents. R1 is an aromatic group which can be substituted or unsubstituted. R2 and R3 are each, independently, hydrogen, an aliphantic group, a substituted aliphatic group, an aromatic group, a substituted aromatic group, an aralkyl group, or a substituted aralkyl group. Alternatively, R2 and R3, taken together with the nitrogen substitutent on the indan ring, form a non-aromatic ring system having 1-2 heteroatoms.
