1. An organic molybdenum complex comprising the reaction product of:
- (i) an alkylphenol chosen from p-octylphenol, p-heptylphenol, p-nonylphenol, p-dodecylphenol, and 2,4-dialkylated phenols, and mixtures thereof, each of which may be further substituted with at least one of halogen, hydroxyl, nitro, amino, alkyl, alkenyl, and alkynyl groups;
(ii) a formaldehyde source;
(iii) an N-hydroxyethyl substituted diamine chosen from 2-(2-aminoethylannino) ethanol, aminopropyldiethanolamine, aminoethyldiethanolamine, and mixtures thereof; and
(iv) a molybdenum source, wherein said molybdenum source is molybdenum trioxide, wherein the N-hydroxyethyl substituted diamine is reacted with the alkylphenol at a molar ratio ranging from 1;
1 to 2;

Abstract
The present disclosure relates to organic molybdenum complexes prepared by reacting a Mannich base with a source of molybdenum. The complexes may be useful in lubricating oil compositions as at least one of an antioxidant, a deposit control additive, and a friction modifier. The organic molybdenum complexes may show a reduced tendency to color finished oils.
