strong bases (n-BuLi, s-BuLi/TMEDA, n-BuLi/t-BuOK, TMPMgCl·LiCl, and LDA) reduce the N═N bond of the parent azobenzene (Y = H), aromatic H→Li permutation occurs with LTMP when a suitable director of lithiation (Y = OMe, CONEt2, F) is present in the benzene residue of the azo compound. The method allows direct access to new substituted azobenzenes.
而标准强碱(n -BuLi,s -BuLi / TMEDA,n -BuLi / t -BuOK,TMPMgCl·LiCl和LDA)会降低母体偶氮苯的N═N键(Y = H),芳香族H→Li当偶氮化合物的苯残基中存在合适的锂化导向剂(Y = OMe,CONEt 2,F)时,LTMP发生置换。该方法允许直接获得新的取代的偶氮苯。
