3,5-Di-tert alkyl-4-hydroxybenzylpyridinium salts are reacted under basic conditions with compounds containing active methylene groups to form phenolic antioxidants. For example, 3,5-di-tert.butyl-4-hydroxybenzylpyridinium chloride is reacted with 2-nitropropane to produce 1,1-dimethyl-2-(3,5-di tert.butyl-4-hydroxyphenyl)-1-nitroethane.
