Abstract

A number of chiral amines were prepared and used as ligands in carbonylchromium(0) complexes. Included are monoamines chelating diamines and methionine methyl ester. For their complexation (norbornadiene)tetracarbonylchromium(0) was found to allow complexation in high, sometimes quantitative yields in boiling THF (65 °C). The amine complexes prepared could be used as complexation reagents for arenes in up to 81% yield in the presence of boron trifluoride-diethyl ether adduct if THF was used as the solvent. Significant chirality transfer from the chiral complexation reagents to the chiral arene complexes was, however, not observed.
