Briefly stated, the present invention comprises a composition of matter having the formula M.sub.x L.sub.y P.sub.z.nQ where M is a metal, P is a counterion, x, y, and z are integers, Q is a solvent, n is a numerical value of from 0 to about 12, and L is either a tris or a bis substituted pyrazolyl borate anion having the structural formula: ##STR1##

Pyrazolyl borates complexes-(LAW294)

A method is provided for preparing organic hydroperoxides by oxidizing aryl alkyl hydrocarbons having a benzylic hydrogen with an oxygen containing gas using as a catalyst an oxo (hydroxo) bridged tetranuclear metal complex having a mixed metal core, one metal of the core being a divalent metal selected from Zn, Cu Fe, Co, Ni, Mn or mixtures thereof and another metal being a trivalent metal selected from In, Fe, Mn, Ga, and Al.

Catalytic production of aryl alkyl hydroperoxides by polynuclear

The present invention relates to a new process for making metal fulleride compositions having the formula A.sub.n (C.sub.x).sub.m, wherein A is a metal cation and C.sub.x is a fullerene anion, preferably C.sub.x is C.sub.60 or C.sub.70, wherein n is a number equal to the absolute value of the valence of the fullerene anion, wherein m is equal to the absolute value of the valence of A, wherein the values of n and m are divided by their greatest common factor, if any, and wherein the metal fulleride composition is neutral in charge. This process comprises reacting a metal with a fullerene in a solvent or mixture of solvents in which the fullerene is at least partly soluble at a temperature from greater than the freezing point to equal to or less than the boiling point of the solvent, for a time sufficient to form the metal fulleride composition. The process has utility in making metal fulleride compositions which may be used as electrode material in reversible electrochemical cells, superconductors, spin labels, magnetic thermometers, organic and polymer precursors.

Method of making metal fulleride

This invention relates to a process for preparing organic hydroperoxides by selectively oxidizing aryl alkyl hydrocarbons to their corresponding organic hydroperoxides using a catalyst certain tetranuclear manganese complexes. The process is carried out without appreciable decomposition by the catalyst of the resulting organic hydroperoxides, and without oxidation by the catalyst of other hydrocarbons present in the starting mixture. The process of the present invention is useful for producing organic hydroperoxides, which themselves are useful as starting materials for a number of commercial reactions, for example, phenol and acetone production.

Catalytic production of aryl alkyl hydroperoxides by manganese complexes

One embodiment of the present invention is based on the discovery of another hexadecanuclear manganese aggregate having a core of 6 barium ions surrounding a carbonate ion. Stated differently, one embodiment of the present invention comprises a composition of matter having the formula:

Manganese oligomer containing main group elements

The present invention is based on the discovery that the previously disclosed tetranuclear manganese compounds are converted into a hexadeca manganese aggregate and a core of 4 barium, 2 sodium and 1 chloride ion. Stated differently, one embodiment of the present invention comprises a composition of matter having the formula:

Briefly stated, the present invention comprises a composition of matter having the formula:

Novel tetranuclear manganese complexes

Bis imidazole ethers have been found to be effective metal deactivators. Thus, one aspect of the present invention comprises novel bis imidazole ethers of the formula: ##STR1## in which R is a normal alkyl group having from 1 to 12 carbon atoms and R' is a normal alkyl group having from 1 to carbon atoms, an alkylaryl group having from 7 to 20 carbon atoms, or an aryl group of 6 to 10 carbon atoms. In another aspect of the present invention, an improved lubricating oil is provided comprising a base lubricating oil and the bis imidazole ethers of this invention.
