Also contains definitions of: acyl anions, acyl cations, acyl radicals, acylium ions
include acyl anions, acyl radicals and acyl cations (synonym acylium ions) which
are formally derived from oxoacidsRkE(=O)l(OH)m
by removal of a hydroxyl cationHO+
, a hydroxyl radical
or a hydroxyl anionHO−
, respectively, and replacement analogues of such intermediates. Acyl anions, radicals
and cations can formally be represented by canonical forms having a negative charge,
an unpaired electron or a positive charge on the acid-generating element of the oxoacid.

Acyl radicals. E.g.
