摘要：
The first five-coordinate, square-pyramidal ruthenium complexes of the general formula [RuCl2(PPh3)(2)L] have been prepared, where L is a phosphoramidite ligand. The new complexes were employed as catalysts for the amination reactions of propargylic esters (18 h, at room temperature or 45 degrees C, Cs2CO3) to give propargylic amines in isolated yields up to 94%.
