The o-lithiation reactions with sBuLi take place regioselectively at the doubly activated C-2 position, which demonstrates the ability of O-carbamates as directed metalating groups. In addition, highly functionalized arylnitriles were accessed from organolithium intermediates by using a tandem transnitrilation/SNAr reaction sequence. spa info:eu-repo/semantics/openAccess ortho-Lithiation Reactions of O-(3,n-Dihalophenyl) N,N-Diethylcarbamates: Synthesis of Dihalosalicylamides and 2,3,n-Trihalophenol Derivatives info:eu-repo/semantics/article
