New planar chiral imidazolium salts such as (S p )-1- [4-(4,4-dimethyl-4,5-dihydrooxazolyl)[2.2]paracyclophane-12ylmethyl]-3-methyl imidazolium bromide (S p )-8a have been synthesized starting from enantiopure 4,12dibromo[2.2]paracyclophane (S p )-4. Deprotonation of these salts followed by reaction

S)-Serine methyl ester is readily transformed into 4-(hydroxymethyl)oxazoline ligands containing either a 2-(h 5 -cyclopentadienyl)(h 4 -tetraphenylcyclobutadiene)cobalt or a 2-(1,2,3,4,5-pentaphenyl)-ferrocene substituent. The influence of the bulky metallocenes result in these ligands mimicking pl
