Meso-[Me 2 Si(2-Me-4,6- i Pr 2 Ind) 2 ZrCl 2 was synthesized in a pure form and used as catalyst for the copolymerization of ethene and α-olefins. The results are compared with polymers obtained by C 1 -symmetric metallocenes and constrained geometr

Upon irradiation of a C2-symmetric rac-isomer of an ansa-zirconocene dichloride, an interconversion into the Cs-symmetric meso-form is observed until a photostationary state between the two diastereomers is reached. The final rac/meso-proportion and
