摘要：
The non-racemic metallated complex derived from tricarbonyl(eta(6)-anisole)chromium 1, formed using the homochiral lithium amide base 2, undergoes rapid racemisation by intermolecular proton transfer if the neutral chromium complex is present, this problem being minimised if the deprotonation is conducted in the presence of LiCl.
