    So there's a plus 1 formal charge on this nitrogen. Obviously, it still has a plus 1 formal charge over here, and we have a plus 1 form or charge over here for this nitrogen. But if we focus in on both nitrogens, this nitrogen is now in the exact same situation as this top nitrogen. They're both actually sp2 hybridized with a Steric number of two.

Die industrielle Chemie der heterocyclischen Aromaten ist außerordentlich vielfältig. Eine Vielzahl von ein- und mehrkernigen Heterocyclen (s. u.) ist im Steinkohlenteer enthalten. Diese Author: Heinz-Gerhard Franck, Jürgen Walter Stadelhofer.

Heterocyclen (aus griechisch ἕτερος heteros ‚anders‘, ‚fremd‘ und lateinisch cyclus ‚Kreis‘; aber auch: Heterozyklen) sind cyclische chemische Verbindungen mit ringbildenden Atomen aus mindestens zwei verschiedenen chemischen Elementen. Der Begriff wird vorwiegend in der organischen Chemie verwendet und bezeichnet eine ringförmige organische Verbindung, deren Ringgerüst.

Da in diesem Fall bereits ein Aromat als Edukt vorlag (1) und das aromatische System nur intermediär aufgebrochen wird (2b), spricht man in diesem Fall von einer Rearomatisierung.

Heterocyclen stellen zu einem hohen Prozentsatz die Grundkörper in Arzneistoffen dar. Aus diesem Grund soll der Diskussion der systematischen Nomenklatur dieser.

Heterocyclic compound, also called heterocycle, any of a major class of organic chemical compounds characterized by the fact that some or all of the atoms in their molecules are joined in rings containing at least one atom of an element other than carbon (C).

The cyclic part (from Greek kyklos, meaning “circle”) of heterocyclic indicates that at least one ring structure is present in such. Tetrahedron Letters No, pp. Pergamon Press. Printed in Great Britain.

Because of the aromaticity of benzene, the resulting molecule is planar in shape with each C-C bond being Å in length and each bond angle being °. You might ask yourselves how it's possible to have all of the bonds to be the same length if the ring is conjugated with both single ( Å) and double ( Å), but it is important to.
