Phenones

Acetophenone

Phenones , also alkylaryl ketones , are mixed aliphatic-aromatic ketones , the most important and simplest representative of this group of substances is acetophenone . If you lengthen the carbon chain by one CH ₂ unit, you get propiophenone . According to a different definition, phenyl ketones have trivial names ending in "-phenon", such as B. benzophenone . Other examples of phenones are acetovanillon and acetosyringone . Hydroxy and methoxy groups sit on the aromatic as further substituents .

Manufacturing

The synthesis of the phenones takes place mostly via the Friedel-Crafts acylation of aromatics (z. B. benzene) with a corresponding acid chloride , z. B. acetic acid chloride or propionic acid chloride .
