Umpolung Amination: Nickel-Catalyzed Coupling Reactions of N,N-Dialkyl-N-chloroamines with Diorganozinc Reagents
摘要:
N,N-Dialkyl-N-chloroamines are an effective source of electrophilic nitrogen for nickel-catalyzed coupling with diarylzinc reagents. A variety of N-chloroamines as well as organozinc reagents react smoothly under the reaction conditions. A one-pot procedure that circumvents the need to isolate the N-chloroamines is described.
