摘要:The present invention is directed to a method of making a ligand which can be used to form an ansa-metallocene. Further, the present invention is directed to a method of making the ansa-metallocene. In both methods the process steps employed to form the ligand are conducted in the presence of tetrahydrofuran, a substituted tetrahydrofuran, tetrahydropyran, a substituted tetrahydropyran or ethylene glycol dimethyl ether.
