亚胺

In this thesis, we developed chiral proton N-O type ligands and employed them in the enantioselective addition of diethylzinc to N-diphenylphosphinoyl imines. The relationship between the structure of the ligands and the enantioselectivity was systematically studied. Furthermore, enantioselective butylation of N-diphenylphosphinoyl imines withBu〓Zn and enantioselective diphenylzinc addition to imine were also examined.

在亚胺化过程中，随酰亚胺化时间的延长，酰亚胺化温度的增高，亚胺化速率变快，亚胺化程度增高。

Seven of them have not been reported.Their structures were confirmed by IR,~1HNMR,MS,and element analysis. 4.Meanwhile,the green methylation procedure of imides was developed by using dimethyl carbonate as methylation reagent.A series of imides,for example,phthalimide,3,4-dibromo-maleimide and succincide were used for substrates.The effects of DABCO(1,4-diazabicyclo [2.2.2]octane)and DBU(1,8-diazabicyclo[5.4.0]undec-7-ene)as a catalyst in this kind of reactions were investigated.2-Bromo-3-(1-methylindolyl-3-yl)-1-methyl-1H-pyrrole-2,5-dione was prepared by using dimethyl carbonate,which further expanded the use of dimethyl carbonate,as a green agent in organic synthesis.

The studies found that compatibility between ZDDP and succinimide dispersants primarily depended upon active α-amino-group content in succinimides. The active α-amino-group content was affected by the alkylation and amination processes, and also affected by the structure of polyisobutylene in succinimides.
