Abstract
This invention provides novel organometallic compositions represented by the general formula: ##STR1## wherein M is selected from the group consisting of members of Groups IIa, IIb, IIIa, IVa and VIIb of the Periodic System of Elements; R.sup.1 is selected from the group consisting of radicals represented by the formula ##STR2## wherein R.sup.2 is selected from the group consisting of hydrogen, hydrocarbyl radicals and heteroatom-substituted hydrocarbyl radicals wherein said heteroatoms are selected from the group consisting of halogen, oxygen, sulfur, nitrogen and phosphorus atoms; R.sup.3 is selected from the group consisting of hydrogen and lower alkyl radicals; R is selected from the group consisting of hydrocarbyl radicals and hetero atom-substituted derivatives thereof wherein said heteroatoms are selected from the group consisting of halogen, oxygen, sulfur, nitrogen and phosphorus atoms; and v, w, x, y and z are integers. Said novel compositions are useful as additives to lubricating oils to provide rust inhibition, sludge dispersant, wear reduction and anti-oxidant properties.
