The chemistry of ferrocene is very rich and covers many areas such as material science, electrochemistry, asymmetric catalysis, etc.1 The unique “sandwich ” structure of ferrocene allows to generate a large variety of chiral compounds featuring a stereogenic plane as the sole chiral element. Among chiral ferrocenes the family of 1,2-disubstituted derivatives is by far the most numerous and a large variety of chiral ligands with different donors share this structural motif. Bidentate pyridine ligands with a stereogenic plane originating from a ferrocene scaffold are very rare and all the known examples possess C2-symmetry.2 Following our long standing interest in chiral ligands with nitrogen donors recently we have devised a viable procedure for the preparation of C1-symmetry bidentate ferrocenyl ligands with pyridine nitrogen donors. 1 (S
