    摘要: A method for deprotecting alkyl arylamine ethers to produce hydroxyl arylamine compounds by reacting the alkyl arylamine ether with a thiolate reagent. More specifically, a method for deprotecting alkyl arylamine ethers to produce hydroxyl arylamine compounds by reacting 2-(diethylamine)ethanethiolate with an alkyl arylamine ether to yield a hydroxy arylamine compound.

    摘要: A process for forming a N,N′-diaryl-N,N′-di(hydroxyaryl)-aryl-diamine compound includes reacting a halogenated aryl compound with an etherified diarylamine in the presence of a catalyst, then deprotecting the resulting N,N′-diaryl-N,N′-di(alkyl-oxyaryl)-aryl-diamine to form the N,N′-diaryl-N,N′-di(hydroxyaryl)-aryl-diamine.
