- The precise pathway to account for specificity is as yet unclarified. Concerted alkylation of an “ate” complex, and/or alkylation of small14 concentrations of the corresponding Li enolate in equilibrium with an “ate” complex are reasonable possibilities
- It has previously been shown that alkylation (C6H5CH2Br, n-C4H9Br) of the internal Li enolate of 2-heptanone produces a mixture of regioisomeric monoalkylates and dialkylation products.3,15
