Benzothiazoline derivatives having the general formula:
wherein R, and R2 may be a hydrogen atom, a hydrocarbyl group, a substituted hydrocarbyl group, an amino group or a halogen atom, a hydroxyl group, alkoxy or aryloxy group, or R, and R2 together may form a cyclic group which may optionally contain a heterocyclic atom; R3 is a hydrogen atom or a hydrocarbyl group; X may be hydrocarbyl, substituted hydrocarbyl, halogen, hydroxyl, carboxyl, amino or amido two X's may be taken together to form a polycyclic compound which may be substituted in line manner; n = 0 or 1-4 are useful as antioxidants for compounds subject to oxidative degradation. The compounds are prepared by reacting an appropriate o-aminothiophenol with a suitable carbonyl compound.
