影響因子Aromaticity is a notion that appeared in the mid-nineteenth century to differentiate between unsaturated hydrocarbons and formally unsaturated benzene [1–3]. At the end of the nineteenth century it seemed that cyclicity was a necessary condition for differentiation between the two, but at the beginning of the twentieth century it turned out that the above assumption was not correct because cyclooctatetraene exhibited typical properties known for polyenes [4]. The essential property of b- zene-like compounds, often identified with aromatic compounds, was low react- ity. Hence thermodynamic stability was defined as resonance energy [5, 6] and was the first quantitative measure of aromaticity. Many theoretical approaches were proposed later to estimate this quantity, and now the criterion is often considered to be the most fundamental [7]. Almost at the same time, magnetic susceptibility was used to describe aromaticity [8, 9]. Consequently, many concepts based on mag- tism were developed, probably the most effective in assessment of aromaticity being nucleus independent chemical shift (NICS) [10] or Fowler’s maps of ring currents [11]. The criterion served Schleyer as a basis for a d

Aromatic Phosphorus Heterocycles,. Thus, in many systems carbon can be replaced efficiently by phosphorus. The versatility is a consequence of the many different bonding modes available for the pnicogen element. The extent of the aromaticity is different with the different bonding modes, and can also be fine tuned by utilizing vari

Chemistry of Hetero Analogs of Pentalene Dianion, simple five-membered heterocycles leading to four structures containing one heteroatom in each ring. The heteroatoms may be the same or different and may be O, NH, S, Se, Te, P, As, or Sb. The fully conjugated hetero analogs of pentalene dianion have a central C–C bond and are isoelectronic with th

William Aspray,Christopher Loughnane, P, PR., As, Sb, Bi, SiR, GeR, BR., and GaR.. Among elements that give rise to aromatic metallabenzenes, so far most investigations have concentrated on Os, Ir, Pt, and Rh. Various qualitative and quantitative aspects of aromaticity are reviewed, such as chemical reactivity, molecular geometry, energetics, and magnetic features.
