A Simple Mnemonic for Tautomerization Mechanisms in Organic Chemistry
Stephens, Chad E.
Journal of Chemical Education, v87 n11 p1186-1187 Nov 2010
The familiar word OREO (as in the cookie) is presented as a simple mnemonic for remembering the basic steps of the classical tautomerization mechanisms in organic chemistry. For acid-catalyzed tautomerizations, OREO stands for proton on, resonance, proton off. For base-catalyzed tautomerizations, OREO stands for proton off, resonance, proton on. (Contains 1 figure.)
