Let be an associative ring with involution . An additive map of into itself is called an involution if the following conditions are satisfied , . A ring equipped with an involution is called an -ring or ring with involution. The aim of the present paper is to establish some results on --derivations in -rings and investigate the commutativity of prime -rings admitting --derivations on satisfying certain identities also prove that if admits a reverse --derivation of , then and some related results have also been discussed.
