Arylaminer

Arylaminer, also known as aromatic amines, are organic compounds that contain an amino group (-NH2) directly attached to an aromatic ring. This structural feature distinguishes them from aliphatic amines, where the amino group is bonded to a saturated carbon atom. The aromatic ring, typically a benzene ring, influences the chemical properties of the amino group, making arylaminer less basic than their aliphatic counterparts due to the delocalization of the nitrogen's lone pair into the pi system of the ring.

The simplest arylaminer is aniline, where a single amino group is attached to a benzene ring. Other common examples include toluidines (methylanilines) and xylidines (dimethylanilines). Arylaminer are important intermediates in the synthesis of a wide range of products, including dyes, pharmaceuticals, pesticides, and polymers. Their reactivity allows for various chemical transformations, such as diazotization, acylation, and alkylation. However, many arylaminer are known or suspected carcinogens, necessitating careful handling and industrial safety measures. Their environmental impact is also a consideration due to their potential persistence and toxicity.
