Sequential reaction of the tricarbonyl[(h 6 -phenyl) carbamate]chromium complex 3 with chiral amide bases (see 4 and 5) and electrophiles yielded planar chiral ortho-substituted complexes 6 with up to 70% enantiomeric excess (ee) (Scheme 2, Table 1 and2). The enantiomer purity could be increased to

Chromium tricarbonyl complexes of 3-methoxybenzyl alcohol and related compounds were selectively lithiated at the 4-position in contrast to the corresponding metal free arene compounds. The resulting I-lithio complexes were converted to the I-substituted arene compounds in moderate to excellent yiel
