N-METHYLAZINIUM -- BENZOANNELATION EFFECT -- ELECTROPHILIC CATIONS
Аннотация: A satisfactory correlation between the polarographic reduction potentials and the calculated energies of the lower vacant molecular orbitals was found for a number of N-methylazinium cations. The result of the aza effect and the benzoannelation effect is a shift of the reduction potentials to the positive region by 0.2-0.5 and 0.2-0.7 V, respectively. Electron transfer from N,N,N′,N′-tetramethyl-p-phenylenediamine to the most electrophilic cations was recorded. The possibility of the occurrence of reactions involving aminoarylation of the acridinium cation via a one-electron mechanism was demonstrated electrochemically and by model reactions

N-METHYLTETRAHYDROQUINOXALINES -- PYRROLE -- IMIDAZOLE
Аннотация: 1H and 13C NMR spectral data for 21 N-methyltetrahydroquinoxalines annelated with furan, pyrrole, imidazole or thiazole rings are reported. Unambiguous assignments of the ring junction 13C resonances were made on the basis of selective decoupling experiments and with the aid of one-bond and long-range 13C–1H coupling constants. The effects of five-membered heterocycles on the 1H and 13C chemical shifts of the ring junction hydrogen and carbon atoms are considered. Values of one-bond 1J(CH) and vicinal 3J(HH) coupling constants between the ring junction protons are also discussed as a diagnostic means for structural elucidation of tetrahydroquinoxalines condensed with five-membered heterocycles.

Аннотация: A series of new tricyclic fluoroquinolones was prepared by replacing fluorine atoms in derivatives of 2-R-8-Y-7-oxo-9,10-difluoro-7H-1,3,4-thiadiazino[6,5,4-i,j]quinoline-6-carboxylic acids. In acids and esters containing a hydrogen atom in position 8 occurred replacement of F10 by amine rests, and in compounds with a fluorine in position 8 was substituted either F8or F10 and F8depending on the amine character

Аннотация: The classical concept of nucleophilic aromatic substitution (SNAripso) has been complemented with a new synthetic methodology (SNH), enabling one to build new carbon–carbon C(sp2)–C(sp3), C(sp2)–C(sp2) and C(sp2)–C(sp) or carbon–heteroatom C(sp2)–X (X is O, N, P, S, halogen) bonds through nucleophilic displacement of hydrogen in an aromatic ring.

Аннотация: The complexation of 3,6-substituted 1,2,4,5-tetrazines with benzotriazole was studied theoretically based on the vibrational spectra. For model complexes, the energy was minimized by the geometrical parameters, and the spectral characteristics were calculated by the PM3 method. The shift of the bond vibration frequencies of the atoms involved in complexation after the formation of different various intermolecular contacts was determined. This made it possible to determine the type of intermolecular interaction and suggest the structures of the complexes
