aromatic substrates. N-Lithio-S,S-diphenylsulfilimine is not only able to displace chloro groups in conventional aromatic nucleophilic substitution reactions, but also, unlike S,S-diphenylsulfilimine itself, can attack at hydrogen-bearing positions in ‘vicarious’ aromatic nucleophilic substitutions of hydrogen.
Ñ -芳基-小号,小号-diphenylsulfilimines不寻常的取代模式已经制备由新颖氮亲核反应Ñ -lithio-小号,š -diphenylsulfilimine与一系列活化的芳族底物。N -Lithio- S,S-二苯基亚
硫亚胺不仅能够取代传统的芳族亲核取代反应中的
氯基,而且与S(S - S-二苯基亚
硫亚胺本身)不同,可以在“毒”的芳族亲核取代基中的含氢位置上发生攻击。氢。
