Abstract
Compounds of the formula ##STR1## and of the formula ##STR2## in which X and X' are, for example, --S--CHR.sup.1, --NR.sup.2 R.sup.3, --S--R.sup.3, --NR.sup.2 R.sup.3 or --OR.sup.3, R.sup.1 is, for example, --H, alkyl, cycloalkyl or phenyl, R.sup.2 and R.sup.3 are, for example, --H, alkyl, cycloalkyl or phenyl, or R.sup.2 and R.sup.3 together form a 3- to 7-membered heterocyclic ring, and R is alkylene, and compositions containing at least one compound of the formulae I and/or II and at least one lubricant, one hydraulic fluid or one metal working fluid, the compounds of the formula I and/or II being used as extreme pressure and wear-reducing additives.
