Ring opening of aziridine with dialkyl amine took place readily in the presence of catalytic amounts of tri-n-butylphosphane (10 mol%) in the mixture of CH_3CN/H_2O(10:1),giving corresponding vicinal diamines in mediate to high yields(58-95%) with good regioselectivitie,while aromatic secondary amine could not react under the same conditions.Tri-n-butylphosphane exhibited different catalytic selectivity to amines from Lewis acid catalysts.
