The Ireland model In the Ireland model, the deprotonation is assumed to proceed by a six-membered or cyclic [ 19 ] monomeric transition state . The larger of the two substituents on the electrophile (in the case above, methyl is larger than proton) adopts an equatorial disposition in the favored transition state, leading to a preference for E ...
