Metal-ligand cooperative iridium complex catalyzed C-alkylation of oxindole and 1,3-dimethylbarbituric acid using alcohols
《Green Synthesis and Catalysis》2023年第3期246-252,共7页Ao Song Yunbo Liu Xuan Jin Dianrun Su Zhaopeng Li Shengsheng Yu Lingbao Xing Xiangchao Xu Rongzhou Wang Feng Li 
support from the National Natural Science Foundation of China(No.22005179);the Natural Science Foundation of Shandong Province(Nos.ZR2020QB113,ZR2020MB018 and ZR2021QB049).
A general and high-efficiency C-alkylation of oxindoles and barbituric acids has been developed by a Cp*Ir complex[Cp*Ir(2,20-bpyO)(OH)]Na with a bipyridine-based functional ligand.In particular,H_(2)O was selected as...

O- and C-alkylations of ethyl nitroacetate with benzyl halides
《Chinese Science Bulletin》1997年第19期1628-1631,共4页Kang, F Yin, HY Yin, CL 
THE chemistry of nitronic esters remains relatively unknown due to their conspicuous feature ofinstability. In the preceding papers, we described the late progress in the researchof nitronic esters: (i) nitronic ester...
