Step 3: Now that you have determined the order of the reactions, identify the missing intermediates in the synthetic scheme. The nitrogen (N)-containing aromatic rings can be separated into basic aromatic rings that are easily protonated, and form aromatic cations and salts (e.g., pyridinium), and non-basic aromatic rings. In the basic aromatic rings, the lone pair of electrons is not part of the aromatic system and extends in the … Zobraziť viac Simple aromatic rings, also known as simple arenes or simple aromatics, are aromatic organic compounds that consist only of a conjugated planar ring system. Many simple aromatic rings have trivial names.
