- Visible-Light-Induced Photoaddition of N-Nitrosoalkylamines to Alkenes: One-Pot Tandem Approach to 1,2-Diamination of Alkenes from Secondary Amines
-
The generation of aminium radical cation species from N-nitrosoamines is disclosed for the first time through visible-light excitation at 453 nm. The developed visible-light-promoted photoaddition reaction of N-nitrosoamines to alkenes was combined with the o-NQ-catalyzed aerobic oxidation protocol of amines to telescope the direct handling of harmful N-nitroso compounds, where the desired α-amino oxime derivatives were obtained in a one-pot tandem N-nitrosation and photoaddition sequence.

- Synthesis and Study of New Clathrochelates with 1-Phenyl-2-(1'-Piperidinyl) Ethanone Oxime Ligand
-
The synthesis and characterization of new complex compounds of [M(L-H)X2], [ML(L-H)]X and [M(L-H)2] types (M = Co, Ni, Cu, X = Cl, CH3COO) and L = 1-phenyl-2-(1'-piperidinyl) ethanone oxime is presented. In reactions of [ML(L-H)]X (M = Ni, Cu) with Lewis acids like TiCl4 and SnCl4 semiclathrochelates of [M(L-H)2M'Cl2] type (M' = Ti, Sn) were obtained and characterized (electronic, FT-IR, RPE, NMR spectra, conductivity measurements, as well as TD-analysis). Such complexes should be potential oxygen molecular carriers.

- STEREOCHEMISTRY OF α-AMINOACETOPHENONE OXIMES STUDY OF SOLVENT EFFECTS
-
The aminolysis of Z-α-halogenoacetophenone oximes results in different mixtures of E- and Z-α-aminoacetophenone oximes depending on the solvent used.Assignment of configuration can be achieved by 13C NMR spectroscopy even if only one isomer is available using a strong solvent dependence of the methylene chemical shift in the case of the Z-isomers.This effect is due to the presence of different conformations in the solvents chloroform and dimethyl sulfoxide.Together with a study by vapor pressure osmometry the results provide an unambiguous proof of intramolecular hydrogen bonding of Z-α-aminoacetophenone oximes in chloroform.
