Treatment of enantiomerically pure, planar-chiral (pS)-1-bromo-2-methylferrocene with phthalimide in the presence of Cu2O yielded (pS)-1-phthalimido-2-methylferrocene, quantitative reduction of which with hydrazine provided (pS)-1-amino-2-methylferrocene with > 99% ee. Formylation of the latter aminefollowed by dehydration of the resulting (pS)-1-formamido-2-methylferrocene furnished (pS)-1-isocyano-2-methylferrocene. The redox behavior of this new planar-chiral isocyanide ligand and its Pd(II) (Figure 1) and Cr(0) complexes will be discussed. In addition, synthesis and coordination chemistry of (pS)-1-isocyano-2-methylcymantrene, a planar-chiral CNR ligand featuring �piano-stool� substituent R will be presented.
