How to pronounce“acylium”in English

In some cases, Friedel-Crafts acylation will work where alkylation doesn’t, because the acylium ion is a slightly better electrophile.

Acylation is usually a more convenient way to add unbranched alkyl groups to a benzene ring, because the acylium ions they form are more stable – and they can’t undergo rearrangement!

The chlorine in acetyl chloride adds to Al-Cl-three to form Al-Cl-four-minus, and a cation known as an acylium ion that is stabilized by resonance.

So in fact, you can make this thing, which is called in an acylium ion.
