Process for converting the achiral meso form or the racemate of an
ansa-metallocene complex or mixtures thereof into one of its enantiomers
摘要:
In a process for converting the achiral meso form or the racemate of an ansa-metallocene complex or a mixture thereof into one of its enantiomers, the conversion is carried out photochemically in the presence of an enantiomerically pure auxiliary reagent.
