本文报道了一种简便的方法，由YCl_3或YCl_3（THF）（3.5）与配体（R）-L ~（-1）和n-BuLi配合，制备高活性和对映选择性的偕二取代氨基烯烃不对称氢胺化钇预催化剂。
A facile method for the preparation of highly active and enantioselective yttrium precatalysts for asymmetric hydroamination of gem-disubstituted aminoalkenes, from the combination of YCl3 or YCl3(THF)(3.5) with ligand (R)-L-1 and n-BuLi is described.
