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

AZINES -- 1,3-BIFUNCTIONAL NUCLEOPHILES -- FURAN -- PYRROLE -- IMIDAZOLE
Аннотация: The literature data on the o-cyclisation reactions of azines with 1,3-bifunctional nucleophiles, which make it possible to annelate furan, pyrrole, imidazole, and other five-membered rings to an aromatic aza-ring are surveyed and described systematically. The cyclisation reactions leading to m-linked cyclic adducts or products of the transformation of azines via the intermediate formation of cyclic m- and p-adducts are also examined.

AZINES -- BIFUNCTIONAL REAGENTS -- CYCLOADDUCTS
Аннотация: Reactions of azines with bifunctional nucleophiles can give rise to several cycloadducts, the structure depending on the nature of reagents, the structure of the azine substrate, and the reaction conditions. Three types of cycloadducts are proposed to be formed in reactions of azines with such 1,3-N,C-dinucleophiles as acetamidines and acetimino esters. Ortho-cyclization products can usually be isolated, while meta- and para-bridged cycloadducts are unstable and are often transformed into other heterocyclic systems. Their presence as intermediates can, however, often is rationalized by spectroscopic methods or 15N-labeling studies. Many of the reactions discussed provide a very convenient synthetic route to a great variety of azine derivatives. It seems to be a very interesting and promising area of heterocyclic chemistry and there is no doubt that further investigations into this field also allow new syntheses of useful compounds to be developed

Аннотация: Reactions of tetra-and pentafluorobenzoyl isothiocyanates with aminoazoles and aminoazines led to the formation of fluorinated 1,3-benzothiazin-4-ones which reacted with cyclic amines in different ways. Replacement of the N=C=S fragment was observed in some reactions of polyfluorobenzoyl isothiocyanates with nucleophiles.
