acyl species

Also contains definitions of: acyl anions, acyl cations, acyl radicals, acylium ions

Acyl intermediates include acyl anions, acyl radicals and acyl cations (synonym acylium ions) which are formally derived from oxoacids RkE(=O)l(OH)m (l ≠ 0) by removal of a hydroxyl cation HO+ , a hydroxyl radical HO. or a hydroxyl anion HO , 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 anions. E.g.
A00129-1
Acyl radicals. E.g.
A00129-2
Acyl cations. E.g.
A00129-3
