Compositions made by reacting (I) a metal phenoxide substituted with at least one hydrocarbon-based group of at least about 30 carbon atoms with (II) a carboxylic acid reagent containing from one to three carboxyl-based groups and a halogen-substituted hydrocarbon-based aliphatic or alicyclic group containing a halogen atom are useful as additives for lubricants and normally liquid fuels. Analogous thiophenoxide-based compositions are similarly useful. These compositions are also useful as intermediates for the preparation of other useful additive compositions through their reaction with alcohols, amino compounds, reactive small ring heterocycles and basically reacting metal compounds.
