ABSTRACT:
Novel dihydrobenzothiophenes prepared via condensation of arylthiols and carbonyl or epoxide containing reagents have been found to be effective antioxidant and antiwear additives in lubricant applications. These additives are made from relatively low cost mercaptans and carbonyl compounds in a one-step high yield reaction.
