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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
