A simple procedure for the preparation of aniline derivatives by the nucleophilic addition of nitrogen anions to x-(arene)chromium tricarbonyl complexes is described. Despite its importance, the number of methods for the introduction of nitrogen-bearing functional groups onto an aromatic ring is qu
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
