Ringing the Changes: Effects of Heterocyclic Ring Size on Stereoselectivity in [(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)RhCl], [(η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)IrCl] and [Ru(η<sup>6</sup>-cymene)Cl] Complexes of Chiral 3-Amino-1-Azacycles.

ABSTRACT: Ring size-dependent diastereoselective coordination of unsymmetrical diamines containing one azacyclic nitrogen and one exocyclic nitrogen to [(η5-C5Me5)MCl]+ cores where M = Rh, Ir and [Ru(η6-cymene)Cl]+ is reported herein. Total stereoselectivity was observed with the six- and seven-membered azacycles, whereas the five-derivative proved poorly selective. All complexes were active for transfer hydrogenation but showed no enantioselectivity with prochiral ketones.
