An antiozonant of formula (I):

##STR00001##

wherein X is selected from the group consisting of O, S, and N; and wherein R is selected from the group consisting of hydrogen, an alkyl moiety, a cycloalkyl moiety, an aryl moiety, an amine moiety, an amide moiety, an alcohol moiety, an aldehyde moiety, a ketone moiety, a carboxylic acid moiety, an ether moiety, an ester moiety, and a thiol moiety. A rubber composition contains the antiozonant, a diene elastomer; a reinforcing filler; a sulfur-based curing agent; and an accelerator for the curing agent.
