摘要：
Mechanistic considerations made a decisive contribution to the development of new chiral P,N ligands L* containing tricarbonylcyclopentadienylmanganese (cymantrene). These ligands induce very high enantioselectives (>99:1) in allylic substitutions of cyclic substrates 1 with formation of 2 (2-Bp = 2-biphenylyl).
