The reaction of N,N-diisopropyl-N-propargylamines with Et3Al/MXn system (MXn = CuCl, CuBr, ZnCl2, ZnI2, CdI2, TiCl4, ZrCl4, VCl5, TaCl5) in CH2Cl2 proceeds as an intramolecular red-ox hydride transfer affording N-dealkylated N-isopropyl-N-allylamines, allenes being formed as side products. The highest chemoselectivities and yields (71–89%) were attained by the application of new
ZnI2/(MeAlO)n system.
