ABSTRACT:
Gamma-alkyl-gamma-butyrolactones having an alkyl substituent of at least 16 carbon atoms in length, preferably at least 25 carbon atoms, are formed by reacting a monoolefin with a carboxylic acid in the presence of a reducible metal ion of higher-valent form, such as the manganic ion, Mn.sup.+3. The resulting lactones are useful as antiwear agents and for improving the adherence of wax coatings of paper and, upon reaction with amines, polyalkylenepolyamines, for providing novel lactams and bislactams useful as multifunctional agents in lubricants, fuels, coolants and other organic fluids. Thus, the compounds of this invention are of the general structure ##STR1## the alkyl group being as defined above, X being oxygen, imino, alkylimino, polyalkylenepolyamino or lactam(polyalkylenepolyamino) and the dangling valences being hydrogen or lower alkyl (that is, no greater than 6 carbon atoms).
