ABSTRACT:
Boron-containing heterocyclic compounds of the chemical formula: ##STR1## wherein at least one of R.sub.1, R.sub.2, R.sub.3, or R.sub.4 is an aryl, alkylaryl, or arylalkyl radical having from 1 to about 30 carbon atoms have been found useful as extreme pressure, anti-wear and friction-reducing additives for lubricating oils. The boron-containing heterocyclic compounds of the present invention are the reaction product of boric acid with the intermediate reaction product of a primary amine and an aromatic oxide. Metal derivatives of the boron-containing heterocyclic compounds are obtained by chemical reaction with a metal or compound thereof, particularly a first row transition metal or a Group IVA metal, or a compound thereof.
