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.
An asymmetric federation however has to have a federal constitution and all states in federation have the same formal status ("state"), while in a federacy independent substate has a different status ("autonomous region").

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".
