Regiodivergent Aromatic Electrophilic Substitution Using Nitrosoarenes in Hexafluoroisopropanol: A Gateway for Diarylamines and p-Iminoquinones Synthesis

A metal-free aromatic electrophilic substitution reaction using nitrosoarenes as the electrophile in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) is reported. HFIP activates nitrosoarene towards the electrophilic C?H amination followed by a concomitant N?O bo

2,5-Diarylamino-N-α(β)-naphthyl-1,4-benzoquinone monoimines undergo oxidative cyclization to give benzannelated phenazinone derivatives.The effect of an N-aryl fragment on the ease of cyclization decreases in the order N-β-naphthyl > N-α-naphthyl > N-phenyl. 2-Arylamino-N-phenyl-1,4-naphthoquinone monoimines do not undergo oxidative cyclization to phenazinones.

Comparison is made between products obtained by oxidation of N-phenyl-1-naphthylamines and 1-naphthyl phenyl nitroxides with peroxyl radicals.It is concluded that oxidation of the amines does not proceed to a considerable extent via the nitroxides.Comparison is also made of products obtained from these amines and nitroxides by oxidation with Fremy's salt.
