Thirdly,in the view of some different results between the reaction of complexes(2)、(3)and[(Me_3Si)_2N]_3LnLi_3 with aromatic aldehydes, the reaction of 2 equiv of aromatic aldehydes with 1 equiv of lithium amide(1) catalyzed by the YCl_3 was subsequently studied,and better yields of the corresponding amides and alcohols can be isolated.These results indicated that the enolate ligand in complexes(2)、(3)may have impact on the Cannizzaro disproportionation reaction.

第三，鉴于上述配合物2、3和[(Me_3Si_2)2_N]_3LnLi_3与芳香醛反应结果上的一些差别，我们又以三氯化钇为催化剂，将两当量的芳香醛与一当量化合物1的锂盐直接进行反应，结果以较好的产率得到了相应的酰胺和醇，这说明配合物2、3中所含的乙烯醇基可能对此Cannizzaro-型歧化反应存在一定的影响。
