Treatment of a 1:1 mixture of meso and racemo isomers of the group 4 bridged-metallocene dichlorides, R<SUB>2</SUB>A(R′<SUB>n</SUB>C<SUB>5</SUB>H<SUB>4−n</SUB>)<SUB>2</SUB>MCl<SUB>2</SUB> (R<SUB>2</SUB> = Me<SUB>2</SUB>, (CH<SUB>2</SUB>)<SUB>4</SUB>; A = Si, Ge; R′ = Me, t-Bu; M = Zr, Hf; n = 1-3) with 0.5 equivalent of amine afforded an μ-oxo complex arising from the meso isomer and left the racemo isomer intact, providing a convenient method of separation of the isomeric mixture.
