Propargylic, allylic and benzylic alcohols prove to be fairly successful as activated nucleophiles, under mild conditions for the SNAr reaction.
在SNAr反应的温和条件下,炔丙基、烯丙基和苄基醇证明作为活化的亲核试剂相当成功。

allene side tethers were tested as substrates for a gold‐catalyzed7‐exo‐trig hydroamination reaction. The nucleophilicity of the aniline derivatives plays an important role for the outcome of the reaction. While electron‐deficient protecting groups at the nitrogen led to competing pathways like hydroarylation or an allene to diene isomerization, clean formation of the desired benzoxazepines was obtained
