Abstract: Coupled amides useful as lubricating additives such as load carrying agents and/or extreme pressure agents have the formula ##STR1## wherein X.sup.1, X.sup.2, and X.sup.3, independently, is O or S; wherein R.sup.1 and R.sup.2, independently, is a hydrocarbyl, a hydro-carbyl-based oxy, or a hydrocarbyl-based thio, having from 1 to about 34 carbon atoms;wherein R.sup.3, R.sup.4, R.sup.5 and R.sup.6, independently, is hydrogen, or an alkyl having from 1 to about 22 carbon atoms, a cycloalkyl having from about 4 to about 22 carbon atoms, or an aromatic, an alkyl-substituted aromatic or an aromatic substituted alkyl having from 6 to about 34 carbon atoms;wherein n is 0 or 1;wherein R.sup.7 is hydrogen or an alkyl having 1 to 22 carbon atoms; andwherein R.sup.8 is an alkylene having from 1 to 12 carbon atoms, phenylene, or an alkyl-substituted phenyl having from 7 to 12 atoms, are useful as lubricant additives such as load carrying agents and/or extreme pressure agents.
