A Ni(II) glycine/Schiff base complex containing (S)-o-[N-(N-benzylprolyl)amino]benzophenone as an auxiliary chiral moiety was deprotonated using electrochemically generated azobenzene radical anion and used in nucleophilic addition to Michael acceptors, terminal 2,2-and 1,2-disubstituted alkenes ((2E)-1,3-diphenylprop-2-en-1-one, (E)-2-nitroethenylbenzene, 2-methylprop-2-enenitrile, Ni(II) dehydroalanine complex), creating a preparatively convenient path for asymmetric functionalization of the α-glycine carbon in the Ni(II) coordination environment, yielding new chiral Ni(II) complexes. The main advantage of the application of electrochemical techniques is the possibility of precise control of the concentration of a base and its in situ reaction with the complex. This opens up the possibility to carry out further functionalization of the anionic adduct formed in Michael addition via a successive one-pot reaction with the other electrophile. A one-pot cascade reaction of electrochemically deprotonated Ni(II) glycinate with (E)-2-nitroethenylbenzene and the successive interaction with benzyl chloride or dimethyl sulfate allowed a new oxime-containing Ni(II) complex to be obtained, which might be considered as an important synthon. All complexes were reliably characterized using HRMS and 1 H and 13 C NMR (including 2D techniques); an adduct with (2E)-1,3-diphenylprop-2en-1-one was also characterized by X-ray diffraction studies and CD spectrum. The manner of stereocontrol in the Michael addition of electrochemically deprotonated Ni(II) glycinate was shown to be different for terminal 2,2-and for 1,2-disubstituted alkenes. In the case of the 1,2-disubstituted alkene both stereocenters are already formed in the first reaction step, which is reversible and thermodynamically controlled. The second step (protonation of the anion) is fast and irreversible, and it does not influence the stereochemical result of the reaction. In contrast to the previous case, only one stereocenter is formed in the first thermodynamically controlled step for terminal alkenes, whereas the configuration of the second stereocenter is determined by a kinetically controlled protonation step.

Herein, we report the synthesis and characterizations of chiral copper(II) coordination polymers (CPs) based on Schiff base of (S)‐2‐aminomethylpyrrolidine and salicylaldehyde derivatives. Single crystal X‐ray analysis showed that copper(II) complex is 1D CP, with the repeating units LCu‐OAc (L=ligand) organized in a perpendicular manner, where the copper(II) atoms are six‐coordinated and have a distorted octahedral geometry. Also complex with chlorine counter ion having unusual dimeric structure was synthesized and characterized. It was demonstrated that CPs catalyze the enantioselective Henry reaction with up to 78% ee.

Fast 2, Eisomebtion of or-nitro-P-indolylacrylates in polar solvents has been studied by dynamic 'H N M R spectroscopy. With indolylnitroacrylates having no substituents at the ring nitrogen atom, isomerhation proceeds via intermediate formation of a mesomeric anion and ionization of the N-H bond as the rate determining step. For methyl-substituted indolylnitroacrylates, no general isomerhation mechanism can be suggested, and isomerization pathways depend on the structures of isomeriziig species.
