Asymmetric federalism or asymmetrical federalism is found in a federation or confederation in which different constituent states possess different powers: one or more of the states has considerably more autonomy than the other substates, although they have the same constitutional status.
An asymmetric federation is similar to a federacy where one of the substates enjoys considerably more independence than the others.
The difference between an asymmetric federation and federacy is indistinct; a federacy is essentially an extreme case of an asymmetric federation, either due to large differences in the level of autonomy, or the rigidity of the constitutional arrangements.

Asymmetric counteranion-directed catalysis
Asymmetric counteranion-directed catalysis (ACDC) or chiral anion catalysis in enantioselective synthesis is ""induction of enantioselectivity in a reaction proceeding through a cationic intermediate by means of ion pairing with a chiral, enantiomerically pure anion provided by the catalyst".
