Benzo[b]perhydroheterocyclic arylamine compounds have shown to be particularly useful as stabilizers. The compounds may serve as antioxidants, antiozoants, heat stabilizers and ultraviolet light stabilizers and such compounds are oil soluble, thus particularly suited for use as an antioxidant in a lubricating oil composition.

A method for ortho-C-H borylation of diphenylamines using BBr3 as the boron source has been reported. The noncatalytic adamantane-1-carbonyl directed reaction exhibited site exclusivity and good functional group tolerance. Generally, the borylation occurred at the more electron-rich aromatic ring and the borylated products could be converted to various useful intermediates. Besides, the derived arylation and removal of auxiliary of the product could be achieved in a one-pot fashion.
