A compound having the structure:
- ##STR13## wherein B is hydrogen or A and A is R--X--;
- X is ##STR14## and R is a hydrocarbyl having about 1 to 100 carbon atoms.
A compound having the structure:
- ##STR16## wherein M is a Group II metal and A is R--X-- wherein X is ##STR17## and R is a hydrocarbyl group having about 1 to 100 carbon atoms.
A process for the manufacture of oil soluble compounds comprising reacting a thiadiazole compound and about 0.5 to 3.0 mole equivalents of a monohydroxy compound and about 0.5 to 2.0 mole equivalent of phosphorous pentasulfide to form a first reaction product and then reacting a 0.5 to 4.0 mole equivalents of mercapto neutralizing compound with the first reaction product per mole of the thiadiazole component in the first reaction product.
