Abstract

Ytterbium and lutetium ionic complexes derived from enantiopure substituted (R)- binaphthylamine ligands, of the general formula [Li (THF) n][Ln [(R)-C20H12 (NR) 2] 2], have been investigated for the hydroamination/cyclization of several aminopentenes and an aminohexene. Complexes with isopropyl or cyclohexyl substituents on nitrogen atoms were found to be efficient catalysts under mild conditions for the formation of N-containing ...
