摘要
We designed and synthesized ligand L1 with C3 synametry in the paper, through self-assembly with silver nitrate obtained complexes 1 of silver double helix with three nuclear, that were used to characterize its structure by NMR and mass spectrometry, the complex silver as the catalytic sites, and the ligand L of hydrogen on the nitrogen fell microphone has certain basic, that can be used as an auxiliary Methylene dehydrogenation of Isopropyl methyl cyanoacetate, thereby accelerating the reaction. Further, the introduction of a chiral ligand to give complexes 2, to achieve an asymmetric aldol reaction of methyl isocyanoacetate.
