ABSTRACT:
Novel compounds of the formula (I) ##STR1## in which X is oxygen or sulfur, R and R.sub.1 independently of one another are C.sub.3 -C.sub.30 alkyl, R.sub.2 is C.sub.4 -C.sub.18 alkyl and R.sub.3, R.sub.4, R.sub.5 and R.sub.6 independently of one another are H, C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 alkenyl, benzyl, phenyl or phenyl which is substituted by C.sub.1 -C.sub.12 alkyl, and in which R.sub.5 and R.sub.6 can also be a direct bond, or R.sub.3 and R.sub.4 together are trimethylene, tetramethylene, ##STR2## and R.sub.5 and R.sub.6 are a direct bond or H, or in each case R.sub.3 and R.sub.6 together are a group .dbd.CH.sub.2 and R.sub.4 and R.sub.5 are H, or R.sub.4 and R.sub.5 together are a group .dbd.CH.sub.2 and R.sub.3 and R.sub.6 are H, or R.sub.3, R.sub.4, R.sub.5 and R.sub.6 together are ##STR3## and salts of these compounds, are described. They can be employed as multipurpose additives, in particular as anticorrosion, high pressure and antiwear additives, and as antioxidants in the lubricants and hydraulic or metalworking fluids.
