摘要：
Sterically hindered hydrazone 2 undergoes an unpredicted N-N bond scission via a methiodination sequence leading to iminium salt 5. This latter compound was found to be remarkably stable under basic and acidic conditions and it proved to be able to promote C-alkylation of the glycine derived imine 7 under classical catalytic liquid-liquid phase-transfer conditions. Both the reaction cleavage and the catalytic potential are discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
