The synthesis of a variety of aromatic amines carrying an ortho‐alkyltelluro group is described. The new antioxidants quenched lipidperoxyl radicals much more efficiently than α‐tocopherol and were regenerable by aqueous‐phase N‐acetylcysteine in a two‐phase peroxidation system. The inhibition time for diaryl amine 9 b was four‐fold longer than recorded with α‐tocopherol. Thiol consumption in the aqueous

A covenient method, developed for the preparation of o-alkyltelluro-benzaldehydes and -phenylketones from o-alkyltellurobenzyl alcohols, involves the intermediate formation and rearrangement of 3H(3R)-benzo-2,1-oxatelluroles, a novel tellurium-containing heterocyclic system.
