A composition comprising: (A) a metal salt of (A)(I) at least one acid of the formula [Figure] wherein each X and X1 is independently oxygen or sulfur, each n is zero or one, and each R1 is independently the same or different hydrocarbon based group, and (A)(II) at least one carboxylic acid of about

A composition comprising: (A) a metal salt of (A)(I) at least one acid of the formula [Figure] wherein each X and X1 is independently oxygen or sulfur, each n is zero or one, and each R1 is independently the same or different hydrocarbon based group, and (A)(II) at least one carboxylic acid of about 2 to about 40 carbon atoms, the ratio of equivalents of (A)(I) to equivalents of (A)(II) being in the range of about 0.5:1 to about 1:0; and (B) an olefinically unsaturated compound capable of reacting with active sulfur. Compositions comprising the foregoing composition reacted with active sulfur are also disclosed. Lubricants and functional fluids comprising the foregoing compositions are disclosed. A process comprising reacting active sulfur with an olefinically unsaturated compound in the presence of component (A) is also disclosed.
