    • Additives for lubricant compositions The invention relates to lubricant compositions comprising at least one compound of the general formula I (I) wherein R1 and R2 are each independently selected from C1-C24alkyl, C1-C24alkyl which is interrupted by one or more identical or different members selected from -O-, -S- and/or -?- ant/or which contains one or more oxo and/or thiono groups; or C3-C24alkenyl, C2-C4hydroxyalkyl, C5-C8cycloalkyl, phenyl or phenyl which is substituted by one or two C1-C12alkyl, C1-C4alkoxy, C2-C2-alkoxy-carbonyl and/or nitro groups; or naphthyl, C7-C10aralkyl, furan-2-ylmethyl or tetrahydrofuran-2-ylmethyl, or R1 and R2, together with the nitrogen atom to which they are attached, form a 5- or 6-membered mononuclear aliphatic heterocyclic ring which, in addition to the N atom, may contain one or two additional N, O and/or S atoms as ring members and/or one or two oxo and/or thiono groups as substituents, or form an indolinyl, 1,2,3,4-tetrahydro-quinolinyl or 1,2,3,4-tetrahydroisoquinolinyl radical which radicals are unsubstituted or substituted by 1 to 3 methyl groups, and R3 is hydrogen or C1-C8alkyl. The N,N-disubstituted S-thiiranylmethylcarbamothioates of formula I are particularly suitable for use as antiwear additives and extreme pressure additives for mineral and synthetic lubricants.
