The invention relates to bisphenyl thiocompounds of formula (I), wherein X1 to X5 independently represent H, Cl, F, OH, SH, R, -OR and -SR, wherein R is an organic radical with 1 to 18 C atoms, which can be an alkyl or alkenyl radical that can also contain -O-, -S- instead of a one to four non-adjacent CH2 groups and that can be substituted once or multiple times by -OH, -SH or halogen, an unsubstituted phenyl, cyclohexyl or cyclohexylmethyl radical or substituted by one or up to three alkyl groups with a total of 1 to 9 C atoms in which a CH2 group may be substituted by, provided that at least 3 of the radicals X1 to X5 arer; Y1 to Y5 independently have the meaning cited for X1 to X5 and Z represents an alpha , omega -alkylene group with 2 to 18 C atoms in which one to three CH2 groups may be substituted by -O- or -S- and 1,4-cyclohexandimethyl group or a simple bond. The invention also relates to the use of said compounds as lubricants.
